Siamese Algae Eaters In Short

Siamese algae eaters are easy to keep fish, as long as you’re keeping them in a big enough tank. They need a pH of 6.5-8.0 and a temperature of 75-79°F. For the best success feed your SAE’s algae wafers and bottom feeder tablets. You can keep them with other fish just make sure the other fish aren’t aggressive.

You can also keep Siamese Algae Eaters on their own or in groups of 5 or more. If you plan on keeping more than one, then each additional SAE will need 10 gallons of water, on top of the first needing 30 gallons.

Keep your tank well planted, with medium lighting, and ensure that the water doesn’t fluctuate as this will stress them massively.

Are Siamese Algae Eater Easy To Keep?

Siamese Algae Eaters are considered relatively easy to keep as they’re hardy fish that can adapt to different water conditions. However, they require a well-maintained aquarium with a suitable environment and diet to truly thrive.

It’s important to provide them with a balanced diet and enough space in their aquarium to swim and explore.

Additionally, Siamese Algae Eaters can be somewhat territorial, so it’s best to either keep them on their own or in groups of at least 5 to reduce aggression and stress. Overall, with proper care and attention, Siamese Algae Eaters can be a great addition to a home aquarium for both beginner and experienced fish keepers.


Siamese Algae Eaters have slender, elongated bodies that are typically silver or gold with a very distinctive black stripe that runs from the head to the tail. Their stripe is thicker in the front and gradually narrows as it reaches the tail, giving them a torpedo-like appearance. 

Siamese Algae Eaters’ fins are clear or translucent, except for the dorsal fin, which can have a slight yellow or orange tint. They have a relatively small mouth, which is located on the underside of their head, with two small barbels (a whisker-like organ) helping them detect tiny prey and changes in their surroundings.


Siamese Algae Eaters are relatively small fish species, typically growing to be around 6-7 inches (15-18 cm) in length. However, they can sometimes grow up to 10 inches (25 cm) in the wild. 

The size of your Siamese Algae Eater may vary depending on the conditions of its environment and its diet. Providing a well-balanced diet and proper care can help ensure that your Siamese Algae Eater grows to a healthy size.


Siamese Algae Eaters are generally peaceful fish that get along well with other community fish. they’re also known to be active swimmers, constantly on the move in search of food.

One of the most notable behaviors of Siamese Algae Eaters is their love for algae. As their name suggests, they’re natural algae eaters and can consume a large amount of algae in a short period of time. They can often be seen clinging to rocks, plants, and other surfaces, picking off any unwanted algae.

In addition to their algae-eating behavior, Siamese Algae Eaters are also known to be jumpers. They have been known to jump out of tanks, so having a tight-fitting lid to prevent them from escaping is crucial.

Siamese Algae Eaters can also be territorial, especially towards their own species. It’s best to provide them with enough space in the tank and to keep them in groups of five or more to help reduce aggression towards each other.


Siamese Algae Eaters have a relatively long lifespan compared to other fish species commonly kept in aquariums. They can live for up to 10 years with proper care and maintenance. However, although they can live up to 10 years, the average lifespan for a Siamese Algae Eater is typically around 5-7 years.

Your Siamese Algae Eater’s lifespan can be affected by various factors such as water quality, diet, and tank conditions. Providing them with a suitable environment, a balanced diet, and a stress-free atmosphere can help them live healthy and long lives.

Water Parameters

Temperature75-79°F (24-26°C)
Tank Size30 Gallons

Siamese Algae Eaters are known to be adaptable and can tolerate a wide range of water parameters, but there are still some ideal ranges that should be maintained for their optimal health and well-being.


Siamese Algae Eaters prefer a slightly acidic to neutral pH range of 6.5 to 8.0.


The ideal temperature range for Siamese Algae Eaters is between 75°F to 79°F (24°C to 26°C).

Water Hardness

Siamese Algae Eaters can adapt to a range of water hardness, but a moderate hardness level of 5 to 20 dGH is ideal.

Tank Size

Siamese Algae Eaters are active and relatively large fish, so they require adequate space to swim and explore. The recommended minimum tank size for a single Siamese Algae Eater is 30 gallons, but for a group of five or more, a larger tank of at least 50 gallons is recommended.

What Do Siamese Algae Eater Like In The Wild?

In the wild, Siamese Algae Eaters primarily feed on algae, as their name suggests. They’re commonly found in fast-moving rivers and streams in Southeast Asia, where they use their specialized mouths to scrape algae off rocks and other surfaces.

Siamese Algae Eaters also consume other small organisms, such as insect larvae and small crustaceans, but algae make up the majority of their diet. In addition to algae, Siamese Algae Eaters also feed on biofilm, a thin layer of organic material that forms on surfaces in aquatic environments.

In their natural habitat, Siamese Algae Eaters are active and fast-swimming fish, requiring a lot of space to swim around. They prefer well-oxygenated water with a strong current, as this helps to simulate their natural habitat and keeps their environment clean.

To create an aquarium environment that mimics their natural habitat, put them in a spacious tank with plenty of swimming room and a strong water flow. A tank with a minimum of 50 gallons is recommended for a group of 5-6 Siamese Algae Eaters, but larger tanks are always better.

Adding plants to the aquarium can also provide good hiding spots for your SAEs and help in replicating their natural habitat. Java moss and Anubias are examples of plants you can add to their tank.

How To Setup A Tank For Siamese Algae Eater 

Setting up a tank for Siamese Algae Eaters requires a few key steps to ensure they have a healthy and comfortable living environment. Here are the factors to consider to ensure their happiness in the tank:

Tank Size

Your Siamese Algae Eaters require a lot of swimming room, so a tank with a minimum of 50 gallons is recommended for a group of 5-6 Siamese Algae Eaters. Larger tanks are even better, as they provide more space and help maintain water quality.

However, if you’re keeping one Siamese algae eater alone, then 20 gallons or bigger is the bare minimum, but 30 gallons is ideal.

Water Quality & Filter

Siamese Algae Eaters thrive in well-oxygenated water with a strong current, so a canister filter or powerhead with a sponge filter can provide the necessary water flow and oxygenation.

Also, regular cleaning of the filter is important to prevent the build-up of organic material and maintain water quality.

Adding plants and driftwood to the aquarium provides hiding spots and mimics the natural environment of Siamese Algae Eaters. Java fern, Java moss, and Anubias are good options due to their ease of care.

Additionally, adding natural sources of algae to the tank, such as rocks covered in algae, can help replicate their native habitat and are great supplemental sources of food.


Siamese Algae Eaters do not require high levels of lighting, but a moderate amount of light can help promote plant growth and keep the tank looking nice.

Tank Mates

Siamese Algae Eaters are peaceful fish and should be kept with other peaceful community fish that are not known to nip at fins or compete for food. So, avoid keeping them with aggressive or territorial fish, as this can cause stress and aggression.


Siamese Algae Eaters are primarily herbivorous with their eating habits, although they are omnivores. They should be fed a varied diet that includes algae wafers, spirulina flakes, and fresh or frozen vegetables such as zucchini or cucumber.

Aside from these, providing natural sources of algae in the tank, such as rocks or driftwood covered in algae, can also help supplement their diet. However, keep in mind, they also eat meat so provide them with live food every once in a while

Siamese Algae Eater Breeding

Breeding Siamese Algae Eaters in captivity can be challenging, as they require specific conditions and triggers to initiate spawning. Additionally, distinguishing male and female Siamese Algae Eaters can be difficult, making it challenging to pair them for breeding. Here are some tips for breeding Siamese Algae Eaters:

Create Ideal Breeding Conditions

Siamese Algae Eaters require specific water parameters to trigger breeding, including slightly acidic to neutral water with a pH of 6.5-8.0 and a temperature between 75-79°F. It’s also essential to provide ample hiding places and vegetation in the tank to mimic their natural habitat.

Distinguish Male and Female Siamese Algae Eaters

It can be challenging to distinguish male and female Siamese Algae Eaters, as they’re not sexually dimorphic. One way to attempt to sex them is to observe their behavior during spawning season, as males may become more territorial and aggressive while females may become plumper with eggs.

Pair Compatible Fish

Once male and female Siamese Algae Eaters have been identified, the next step is to pair them in a breeding tank. It’s best to pair compatible fish with similar sizes and temperaments to reduce stress and aggression.

Provide Optimal Nutrition

To encourage spawning, It’s crucial to provide Siamese Algae Eaters with a balanced and nutritious diet. In the wild, Siamese Algae Eaters feed on algae and plant matter, so offering a variety of vegetable-based foods such as spirulina, algae wafers, and blanched vegetables can help promote spawning.

Monitor and Observe

Breeding Siamese Algae Eaters can take time and patience. Monitoring water quality and conditions regularly and observing the behavior of the fish should be practiced. Once eggs are laid, they will hatch in about 3-5 days, and the fry will be able to swim freely after about a week. It’s important to separate the fry from the adults, as they may be eaten or outcompeted for food.

Siamese Algae Eater Common Diseases 

Siamese Algae Eaters are generally healthy and hardy fish, but they can still be susceptible to certain diseases and conditions if their care is not optimal. It’s important for fish keepers to be aware of these common issues so they can recognize and address them quickly.


Ich is a parasitic infection that can affect many types of fish, including Siamese Algae Eaters. It’s caused by a protozoan parasite that attaches to the fish’s skin and fins, causing white spots or cysts. The parasite can also cause irritation, inflammation, and damage to the fish’s gills.

Ich can be treated with medication, such as copper-based or formalin-based remedies, but to be successful in treating them, follow the instructions carefully and monitor the fish closely.

Fin Rot

Fin rot is a bacterial infection that affects the fins and tail of the fish. It can be caused by poor water quality, fin injury, or stress. The affected fins may appear ragged, frayed, or shredded, turning white or opaque at the edges. In severe cases, the fins may even rot away completely. 

Antibiotic medication can be used to treat fin rot, but the underlying cause should be addressed first, such as water quality and stress.

Velvet Disease 

Velvet disease is caused by a parasitic protozoan that can affect Siamese Algae Eaters, among other fish. It presents as a yellow or gold dust-like coating on the fish’s body and fins and can also cause lethargy, loss of appetite, and respiratory distress. Velvet disease can be fixed using medication, such as copper-based or formalin-based remedies.


Dropsy is a symptom of an underlying condition, often a bacterial infection, that can affect Siamese Algae Eaters. It presents as bloating or swelling of the fish’s body and may also cause pineconing of the scales, lethargy, and loss of appetite. Dropsy can be difficult to treat and often requires antibiotic medication and improved water conditions.

Swim Bladder Disorder

Swim bladder disorder can be caused by a variety of factors, including overfeeding, constipation, or injury. It affects the fish’s ability to regulate buoyancy and swim properly and may present as the fish swimming upside down, floating at the surface, or having difficulty swimming. 

Swim bladder disorder can usually be treated with improved diet and water conditions, such as reducing feeding frequency or providing high-fiber foods.
