Tropical Fish A-Z

Last Updated on 2023-08-31



Barbs are an extremely popular group of tropical fish. They’re schooling fish, so if you plan on keeping them, keep them in groups of at least 5-6. They’re also very active swimmers in the tank, so generally, they need at least 20 gallons of tank space or more!

And to truly make them happy, the tank should have plenty of plants and hiding places to provide the barbs with a sense of security.

Barbs are usually found in the middle to upper levels of the tank. However, they’re not shy fish, and they will often swim around the tank. Some species can also be aggressive towards other fish that are smaller or slower than them. So make sure to choose tank mates carefully.

If you plan on choosing catfish for your tank there are actually a number of different choices! So you should decide which catfish you want from the following!

Corydoras Catfish

Types Of Corydoras Catfish

Corydoras catfish are some of the greatest fish for your tank, especially if you’re jut starting out. This is thanks to how peaceful and hardy they are, as well as how easy they are to care for. There are also so many different varieties of them to choose from, so you really are spoilt for choice!

Like all catfish, Corydoras catfish are bottom-dwelling fish, so they will spend most of their time swimming near the substrate. They also prefer to be kept in groups, so make sure you’re keeping at least 5-6 together.

The ideal tank size for corydoras catfish, does depend on the species but generally 20 gallons or larger is going to be best. The tank you keep them in should have plenty of plants and hiding places, such as rocks, driftwood, and caves.

Plecos, also known as suckermouth catfish, are a staple of most aquariums thanks to how easy to care for they are. There are over 150 species of plecos, but some of the most popular include the common pleco (Hypostomus plecostomus), the bristlenose pleco (Ancistrus sp.), and the rubberlip pleco (Otocinclus affinis).

Plecos are bottom-dwelling fish, so they’ll spend most of their time near the bottom of the tank, where you’ll see them sucking algae off the glass of your tank and driftwood! They’re also nocturnal, so if you want to see them when they’re most active, you’ll need to catch them at night.

One important thing to note about keeping plecos is that they often need large tanks. While smaller species like the bristlenose pleco can live in tanks that are 30 gallons or bigger, larger species may need tanks that are 150 gallons or bigger!

They are also long lived fish, so buying them is no small investment. It’s not uncommon for them to live 20 years or more!

Upside Down Catfish

Upside down catfish are some of the most unique and interesting tropical fish you can add to your tank, however, they aren’t as commonly seen as most catfish. As you can guess by their name, what makes them so unique is that they like to swim upside down!

If you want to add upside down catfish to your tank, make sure you’re adding lots of driftwood and large leafed plants, as they like to spend most of their time foraging for algae on the undersides. And when you’re choosing a tank for them, make sure you’re picking a tank which is 30 gallons or larger.

Other Catfish

Glass Catfish

Another truly fascinating fish to keep are glass catfish! As you can guess by their name, they’re almost see through, however, it’s important to note that as their name suggests, they’re also very fragile, so they should be kept by more experienced fish keepers!

Unlike other catfish, glass catfish aren’t bottom-dwellers and prefer to spend their time in the mid levels of the tank. On top of this, they’re also schooling fish, and they are going to be a lot more likely to survive in schools of 6 or more!

If you do plan on keeping glass catfish, you’ll need to make sure that the tank is at least 30 gallons, and due to their peaceful nature it should be full of plants, driftwood and other hiding places.

With proper care, your glass catfish can live for 6-8 years. However, again, it’s important to remember, that they are fragile fish, so caution must be taken when keeping them.

Twig Catfish

Twig catfish (Farlowella spp.) are a group of small, slender catfish that are native to South America. They’re most known for their long, thin bodies and their ability to camouflage themselves against driftwood and other objects in the aquarium, however, they’re not often seen in most hobbyists tanks.

Twig catfish are peaceful fish so you can keep them in community tanks. Just make sure you’re keeping them with other peaceful fish. One thing to note is that they’re not the most active fish, so if you do plan on keeping them, don’t expect too much from them.

The ideal tank for twig catfish is a planted tank with a sandy substrate. The tank should be at least 20 gallons in size, and it should have plenty of hiding places for the fish to feel secure.

Lastly, twig catfish are not difficult to care for, and they make good additions to community tanks. With proper care, they can live for 10-12 years.

Whiptail Catfish

Whiptail catfish are another species of peaceful catfish that are great for community tanks. They’re not very active, and they prefer to spend most of their time hiding in plants or driftwood. They are also relatively hardy fish, and they can tolerate a wide range of water conditions.

The ideal tank for whiptail catfish is a planted tank with a sandy substrate. The tank should be at least 30 gallons in size, and it should have plenty of hiding places to keep them feeling secure.

Fortunately whiptail catfish are not difficult to care for, making them great additions for community tanks. When given proper care, you can even expect them to live for up to 8 years!

Pictus Catfish

Pictus catfish are schooling fish, so keeping one isn’t going to be enough, you’re going to need to keep 5-6. This on top of the fact they’re active swimmers, and can grow up to 5 inches in length means that you need to keep them in tanks which are at least 55 gallons in size or larger.

The ideal tank for pictus catfish is a planted tank with a sandy substrate and plenty of hiding places. Remember, the more hiding spots, the more comfortable your fish will feel, and the more likely they are to be active in the tank.

Pictus catfish are not difficult to care for, so if you’re just starting out and you want a unique looking fish for your tank, then they could be your newest addition!


Cichlids are a large and diverse group of freshwater fish known for their colorful and varied appearance, complex social behavior, and their ability to adapt to a wide range of water conditions.

Cichlids come in all shapes and sizes, from the tiny dwarf cichlid, which only grows to be a few inches long, with the largest cichlid (Boulengerochromis microlepis) growing up to 3 feet in length! They are also found in a wide variety of colors, including red, blue, green, yellow, and orange.

Cichlids are social fish, and they often form dominance hierarchies. They are also territorial, and they may fight with other fish for food or breeding rights. However, there are also many peaceful cichlid species that make great community fish!

If you do plan on keeping Cichlids, it’s important to remember that while they’re not difficult to care for, they can be aggressive.

Angelfish are relatively large fish, reaching up to 6 inches in length and 8 inches in height at maturity. While they’re not schooling fish, they do like to live in pairs or groups, so try to keep two together minimum.

They’re also extremely active, so you should make sure the tank is big enough. In fact, the tank should be 55 gallons in size, and heavily planted to provide them with enough hiding spots.

Angelfish are not difficult to care for, however, due to the size they can grow too I wouldn’t recommend them for beginners. And while they’re mostly peaceful fish, they can be territorial, espcially when they don’t have enough space

Dwarf Cichlids

Dwarf cichlids typically grow to be no more than 4 inches in length, making them ideal for smaller aquariums. They’re also relatively easy to care for, making them a good choice for beginners!

Dwarf cichlids are social fish, and they do best when kept in groups of at least 3 or 4, with one male for every 2-3 females. They’re also territorial, so make sure to provide them with plenty of hiding places in the aquarium. The ideal tank for dwarf cichlids is a planted tank with a sandy substrate. The tank should be at least 10-20 gallons in size,

Dwarf cichlids are omnivores, and they will eat a variety of foods, including flakes, pellets, frozen food, and live food. They should be fed a diet that is high in protein.

Danios are small, hardy, and active freshwater fish, and in fact, some of the most popular amongst fish-keepers.

They’re schooling fish, that do best in groups of at least 5 or more. And because of how active they are you should keep them in a tank that favours length over height.

The ideal tank for danios is a planted tank with a sandy substrate. The tank should generally be at least 20 gallons in size (however, this depends on the type), and it should have plenty of hiding places for them to feel secure.

They’re peaceful fish, that won’t bother other tank mates which makes them great for community tanks. However, the only time this isn’t the case is when the tank is too small, and then they may become fin nippers.

Freshwater Pufferfish

Freshwater Pufferfish are less talked about, but they’re great if you’re just getting started and want something cool! They’re generally hardy fish, so as long as you’re keeping the water parameters stable they’re going to be happy!

Freshwater Pufferfish are active fish however, so they’ll need plenty of space to swim and explore. A minimum tank size of 10 gallons is recommended for smaller species, such as pea puffers. Larger species, such as the Fahaka puffer, may require a tank as large as 100 gallons.

One thing to note is that they’re extremely territorial, and often kill other tropical fish in their tank. So if you do want to keep them, you can only keep them with their own kind.

Types Of Gobies

Gobies are bottom-dwelling fish that prefer to stay close to the substrate. They have a suction cup-like disc on their pelvic fins that allows them to cling to rocks and other surfaces.

They’re also peaceful fish, which makes them great for community tanks. However, some species of gobies can be territorial, so it is important to do your research before adding them to your tank.

Gobies do not require a lot of space, but they do appreciate having plenty of hiding places. A good-sized tank for a group of gobies would be 10-20 gallons or larger.

The substrate in the tank should be soft and sandy, as gobies have sensitive mouths. You should also add plenty of live plants to the tank, to give your gobies lots of shelter!

Gouramis are a group of freshwater fish that are native to Southeast Asia. They are known for their labyrinth organ, which allows them to breathe oxygen from the surface of the water, however, it’s still better to give them well oxygenated water.

Gouramis come in a wide variety of shapes and sizes, from the tiny honey gourami, which only grows to be about 2 inches long, to kissing gouramis, which can grow to be over 12 inches long. They are also found in a wide variety of colors, including blue, green, yellow, and orange.

It’s also important to note that while for the most part, the majority of gouramis, can be kept in community tanks, as long as you make sure you’re not keeping them with fish that look like them, or other aggressive fish.

Hatchet Fish

Hatchet fish are small, freshwater fish native to South America. As their name suggests, they have small flat bodies, looking similar to a hatchet.

Hatchet fish are schooling fish, so they do best when kept in groups of 6 or more. You also need to keep in mind that they are active swimmers, so even though they’re not big fish, they will need a lot of space.

Hatchetfish are not difficult to care for, and they make good additions to community tanks. They are peaceful fish, and they will not bother other tank mates. However, they can be nippy, so it is important to provide them with plenty of space.


Types Of Killifish

Killifish are typically shy fish that prefer to stay in the middle to lower levels of the tank. Fortunately, though, they’re not aggressive fish and make grest tank mates for other small, peaceful fish.

And because of their small size, they don’t typically need to be kept in big tanks, anything from 10-20 gallons is enough. And they can live for 2-5 years with proper care.

With all this in mind killifish are a great choice for beginner fish keepers.

Knifefish are a group of freshwater fish that are native to South America. Mostly known for their unique elongated bodies, these fish often need upwards of 120-180 gallons to truly thrive.

Knifefish are not difficult to care for, but they are not for beginners. They require a specific setup and diet, and they can be sensitive to water quality.



Livebearers are a group of fish that give birth to live young, rather than laying eggs. They’re some of the most popular aquarium fish, and for good reason. They’re super easy to care for, come in a wide variety of colors and patterns, and are often very hardy.

Some of the most popular livebearers include guppies, mollies, platies, and swordtails. They are all relatively small, typically growing to be only a few inches long (although mollies can grow 4-5 inches). They’re also all peaceful fish, making them good choices for community tanks.

Endler’s Livebearer’s

Endler’s livebearers are a great choice for beginners just getting started in the trade thanks to how easy they are to care for! They’re slightly smaller than guppies but breed just as much.

If you do plan on keeping them, then try a 10 gallon tank and make sure that you have a way of dealing with the fry that inevitably follows.


Voted the easiest fish to keep by 150 fishkeepers, guppies are another great choice for anyone starting out. They look fantastic and are generally hardy! Just make sure that you’re buying them from a reputable breeder, as inbreeding has made some variants weak.


If you’re looking for something bigger, then mollies are a great choice. Again, incredibly peaceful, whilst also coming in a variety of shapes and sizes, so you can find some truly unique looking ones for your community tank!


I love platies, and they were some of the first fish I ever took care of. Again, all you have to do it out them in your tank, feed them and keep the parameters good in they’ll be happy!

One thing to note, like all livebearers if you don’t have other fish to eat their fry, then you may end up with more than you bargained for.


Lastly, some of the most unique looking fish you can add to your tank, swordtails, are also a great choice. As you can guess, their tail looks like a sword (however this is only the males)

While they are livebearers they don’t produce fry as often as the rest. And if you do plan on keeping them, make sure to keep them in a 20 gallon tank or bigger.

Loaches are another diverse group of freshwater fish that are found mostly in Asia, with a couple of species being found in Europe, and Northern Africa.

Loaches come in a wide variety of shapes and sizes, from the tiny hillstream loach, which only grows to be about 2 inches long, to clown loaches, which can grow to be over 12 inches long. They are also found in a wide variety of colors, including silver, gold, black, and striped.

Loaches are generally peaceful fish, and they make good additions to community tanks. However, some species, such as the clown loach, can be aggressive, so it is important to choose loaches that are compatible with each other.

Pencilfish are a group of small, slender freshwater fish that are native to South America. They are known for their long, thin bodies and their peaceful nature.

Pencilfish are schooling fish, so they do best when kept in groups of at least 6 or more. They are also relatively active fish, so they need a spacious tank with plenty of swimming space.

Pencilfish are also easy to care for and make great additions to community tanks. Most of the time they’re peaceful, however, they can be nippy when their basic requirements aren’t being met.

Types Of Rainbowfish

Rainbowfish are a family of small, colorful freshwater fish native to Australia, New Guinea, and Indonesia. They are known for their iridescent scales, which change color depending on the light.

Like other fish, they’re schoolers so make sure you’re keeping them in groups of 6 or more and because they’re active fish, they’ll also need a spacious tank with plenty of swimming space.

Rainbowfish aren’t difficult to care for at all, and they’re great additions to community tanks.

Again, most rasboras are not difficult to care for at all, and they’re some of the best fish you can add to a community tank. They’re mostly peaceful, just make sure that you’re keeping them with other peaceful and similarly sized fish and you’ll have no problems looking after them!

Freshwater Sharks

Freshwater sharks are not actually sharks, in fact, they’re in the same family of fish as carps and minnows.

One thing about freshwater sharks is that they need a large tank with plenty of swimming space. The ideal tank size for a freshwater shark will vary depending on the species, but most species will need at least a 55-gallon tank.

It’s also important to remember that most freshwater sharks are semi-aggressive and territorial, so if you’re going to keep them, you need to make sure you’re picking the right tank mates for them.

Other Fish

Silver Dollar

Silver Dollars can grow to be up to 10 inches long, so they require a large tank. A 55-gallon tank is the minimum size for one Silver Dollar, but a 125-gallon tank is ideal. Silver Dollars are also messy fish, so the tank should be well-filtered.

Silver Dollars are not difficult to care for, and they make good additions to community tanks. They are peaceful fish, and they will not bother other tank mates. However, just remember that they grow incredibly large, so make sure you’re giving them plenty of space in the tank.

Red Pirahna

Red piranhas are a species of freshwater fish that are native to South America. They are known for their sharp teeth and their aggressive behavior. However, red piranhas are not as dangerous as they are often portrayed. In fact, they are mostly scavengers and will only attack if they are provoked or feel threatened.

Red piranhas can grow to be up to a foot in length, so they require a large tank. A 100-gallon tank is the minimum size for a group of red piranhas, but a 200-gallon tank is ideal. Red piranhas are also messy fish, so the tank should be well-filtered.

Red piranhas are not difficult to care for, but they are not recommended for beginner aquarists. They are best suited for experienced aquarists who are willing to provide them with the proper care.

Gray Bichir

Gray Bichir are a species of freshwater fish native to Africa. They are known for their long, eel-like bodies and their ability to breathe air, almost looking prehistoric.

Gray bichirs can grow to be up to 24 inches long, so they require a large tank. A 75-gallon tank is the minimum size for a single gray bichir, but a 125-gallon tank is ideal. Gray bichirs are also messy fish, so the tank should be well-filtered.

While they’re not particularly difficult to care for, due to their need for large tanks and powerful filters, they’re not recommended for beginners.

Barred Bichir

Barred bichirs can grow to be up to 14 inches long, so they require a large tank. Because of their large size, and the fact they are messy fish, they need to be kept in tanks that are 125 gallons or bigger with powerful filtration.

Japanese Ricefish

Japanese ricefish are small fish only growing to be about 1.5 inches long, so they can be kept in relatively small tanks. A 10-gallon tank is the minimum size for a group of Japanese rice fish, but a 20-gallon tank is ideal.

If you’re just starting out and you’re looking for a unique and easy fish to keep, then these are going to be a great choice!

Freshwater Shrimp


As well as fish, there are also freshwater shrimp to choose from as well! In fact, there are a whole range of species that come in different colors, shapes and sizes!

In fact, they’ve become so popular there are even difference grading and ranking guides for certain species!

While they are small, you should rarely house them in a tank smaller than 5 gallons, although a lot need 10 gallons or more! Some species are also susceptible to poor water conditions as well. If you’re just starting out stick to cherry shrimp, amano shrimp, or ghost shrimp.

Freshwater Snails

As well as freshwater shrimp, you should also consider freshwater snails. They can be found slowly moving around the tank looking for algae to eat. And sometimes, they can be introduced into the tank simply by adding new plants.

Snail populations can grow out of control, so if you do plan on adding them it’s a good idea to go for a species that doesn’t breed as often like rabbit snails or Malaysian trumpet snails.

And if your snail population does get out of control, you can also add assassin snails as well!
