What Are the Different Types Of Rasbora?
Here are all the different types of rasbora you should consider adding to your tank! Personally I love chili rasboras for beginners thanks to how small they are, and the ease of care they require. However, if you are just starting, you can also try harlequin rasboras and lambchop rasboras.
Red-tailed/Black Line Rasbora
A peaceful, robust, and hardy fish, the Blackline Rasbora, or Rasbora Borapetensis, can live with other temperate breeds. They are a schooling fish, congregating in a tight group that darts back and forth. So, there should be at least six.
Blacklines are silver with a dark brown or black lateral stripe. This starts at the gill opening and runs to the base of the right red caudal fin. Above that is a gold bar. Blacklines can live for up to seven years.
These fish come from the areas around Thailand, Cambodia, Laos, Vietnam, Malaysia, China, and beyond. They prefer shallow, slow-flowing water with lots of plants in ditches, ponds, canals, swamps, drains, and reservoirs.
These rasboras eat a balance of both vegetation and meat. In captivity, they accept flakes, pellets, and granules, as well as meats like artemia, tubifex, mosquito larvae, bloodworms, and daphnia.
| Name | Red Tailed Rasbora/Blackline Rasbora |
| pH | 6.5-7.0 |
| Temperature | 72-79°F |
| Tank Size | 20 Gallons |
| Size | 2.6″ |
| Lifespan | 5-7 Years |
Chili Rasbora/Mosquito Rasbora
Chili Rasboras, or Boraras Brigittae, are the least ideal for a community tank because of their small size and timid nature. However, when kept with others like them, they’re peaceful and easy to care for. Chilies prefer to be in a school with at least 6 fish, although you can keep them in schools of 20 too! and can live for up to eight years.
These fish have reddish bodies with a dark stripe on the side. An intense red bar sits above this stripe, creating a gorgeous contrast. They also have red highlights on their anal and dorsal fins.
They come from Borneo with a love for blackwater environments in places like swamps, streams, rivers, and pools. This means they love tannin-rich waters with leaves, twigs, and branches.
They aren’t picky eaters but like a varied diet. This should include high-quality pellets, crushed flakes, and meats like bloodworms, cyclops, and brine shrimp.
| Name | Chili/Mosquito Rasbora |
| pH | 5.0-7.0 |
| Temperature | 72-82°F |
| Tank Size | 5 Gallons |
| Size | 0.8″ |
| Lifespan | 4-8 Years |
Clown Rasbora
Clown Rasboras, also called Rasbora Kalochroma, are very peaceful and love being in groups of eight to 10. These are great in a community tank so long as their tank mates are about the same size and temperament. However, it’s important to note that males will be aggressive from time to time.
Clown rasboras are pinkish-red and have two large, dark splotches on their bodies. One is behind the gill cover, and the other is on the middle area of the flank, between the anal and dorsal fins. Some even have a row of spot-like markings that connect the two dark splotches.
Clown rasboras come from places like the Malay Peninsula and the Greater Sunda Islands. They love acidic and soft streams, rivers, and peat swamps. So, their environment should be tannin-rich. This also means they love shady, low-light tanks, so try adding some floating plants like duckweed to your tank as well.
They can live for up to five years and enjoy a meat-heavy diet. Things like frozen or live daphnia, bloodworms, and artemia, along with granules, freeze-dried foods, and dried flakes are all great choices.
| Name | Clown Rasbora |
| pH | 5.0-7.0 |
| Temperature | 75-82°F |
| Tank Size | 30 Gallons |
| Size | 4″ |

Exclamation Point/Least Rasbora
Although a very peaceful and hardy fish, Exclamation Point Rasboras, or Boraras Urophthalmoides, don’t do well in a community tank, unless they’re kept in a tank with other fish that are a similar size to them (otherwise, they may end up being bullied).
They do best in a school of eight or more and can live for up to eight years. Males will aggressively compete for females, but they also display some of their best colors when they’re in this excited state.
Exclamation Point Rasboras have golden yellow bodies with a dark green or brown stripe along the sides that ends just behind the dorsal fin. There’s also a distinct round dark blotch on the caudal peduncle. The placement of these markings resembles an exclamation point, hence the name. Some actually develop an intense orange-red line above the lateral stripe.
Exclamation Point Rasboras come from the southern peninsula of Thailand where they live in slow flowing water in rice paddies, marshes, ponds, swamps, and peat bogs; anywhere that has heavy vegetation. This means the water is slightly acidic, soft, and tannic.
You can mimic this in their tank by adding lot of plants like anubias and java fern, as well as making sure the filter current isn’t too powerful.
In captivity, they eat micro pellets and crushed flakes along with daphnia, brine shrimp, artemia, cyclops, and bloodworms.
| Name | Exclamation Point Rasbora |
| pH | 6.6-7.5 |
| Temperature | 72-78°F |
| Tank Size | 10 Gallons |

Fire Rasbora
Fire Rasboras, also known as Rasboroides Vaterifloris, are very timid. For security, they need a group of eight or more and they do a lot better in species only tanks. However, if there are other breeds that are similar in size and temperament, they will be okay.
When it comes to how long they’ll live, they have a lifespan of around five years.
Fire Rasboras are small, slender, and oval with a forked caudal fin. They have pale orange bodies with rich red in the fins. Their body and fin colors can vary depending on their native habitat.
The color can range from blue to red, depending on the part of their body, and the fins can be several colors. But, orange, yellow and red are most desirable.
Fire Rasboras hail from the southwestern area of Sri Lanka. They inhabit clear, slow-moving, and shallow streams, lakes, and river basins. The habitats the tend to live in have silt or sand substrates covered in leaves, twigs, and branches. Because these areas rest under forest canopies, Fire Rasboras love the shade and low-light situations in their tank.
They thrive best on a well-rounded diet the bulk of which coming from fish granules and flakes. But, they should also have daphnia, bloodworms, and artemia on ocassion.

Glowlight Rasbora
Although small, the Glowlight Rasbora, otherwise known as Trigonostigma Hengeli, is an eye-catching addition to a peaceful community tank. They have an exciting, engaging, and fast-paced lifestyle that’s entertaining to observe. They should stay in a school of eight or more with plenty of plants for maximum happiness.
Glowlights have colors ranging from ivory to pinky-blush orange or coral. They have a distinct lemon yellow color on their fins with a brilliant neon orange stripe above a thin black marking on their flanks.
Unfortunately, they have a short lifespan compared to other rasboras and only live for up to three years.
They live in the area between the Malay Peninsula into Singapore along with the Greater Sunda Islands, Borneo, Thailand, and Cambodia. In the wild, massive schools will fill an entire stream. Heavy vegetation with slightly acidic, calm, and soft water is their ideal habitat.
So when you add them to your tank remember the water should also have a yellowish-brown color, provided by tannins from driftwood and leaves.
Just like other rasboras their diet is simply. They enjoy meaty meals of bloodworms, artemia, and daphnia, but the bulk of their diet should come from quality flakes and granules.

It’s best to keep Harlequins in a school or six or more, and you should also bare in mind they can live up to five years.
Harlequins have a black triangle-like shape beginning at the dorsal fin and continuing to the tail. All fins line with red amid orange-silver bodies.
These fish come from southern Thailand, Malaysia, and Singapore Sumatra. The ideal environment is one with slow-flowing water that’s soft, calm, and with a pH that’s slightly acidic neutral. When adding them to your tank remember that not only do they need this, but also plenty of plants and hiding spots.

Neon Green Rasboras, also called Microdevario Kubotai, are peaceful and hardy. This makes them great additions to well-planted aquariums in schools of eight to 10. The larger the school, the less nervous they will be and it may also help them reach their maximum lifespan of seven years!
They aren’t always good for a community tank because of their timidity, so they should either stay alone or with other breeds that are equally timid and peaceful. And if you do plan on adding them to your tank add lots of plants and keep the lighting dim.
Neon Green Rasboras have gray-olive bodies with green-yellow iridescence. They also have a metallic-looking yellow-gold lateral stripe with translucent dorsal and anal fins.
Neon Green rasboras come from several areas around Thailand and southern Myanmar. This means they love calm to moderate water movement with plenty of plants, driftwood, vegetation, and a rocky substrate.
These fish are not picky eaters and accept flakes, granules, and pellets. But, some meat should also be in their diet, like brine shrimp, daphnia, insect larvae, and bloodworms. They also like blanched greens like zucchini, kale, and lettuce.

Phoenix Rasboras, or Boraras Merah, are very stunning fish with a calm disposition. But, they aren’t ideal for community tanks because of their shyness. If housed with other timid fish, they’ll be fine. But anything bigger or more aggressive will cause them to flee and hide. They do best in groups of eight or more.
Phoenix Rasboras have a black line running down the sides of their bodies with a bright orange-red color base. But the more vibrant aspects are really pop around the black. The rest of the body tends to be a little bit more dull, however, they’re still beautiful fish.
Their home is in Borneo so to replicate this try to create a heavily planted, low-light environment with a soft, sandy substrate. Phoenix rasboras love blackwater, which means their environment should be tannin-rich with plenty of branches, twigs, and leaves.
They can live up to five years and have hearty appetites. While not fussy, they thrive on a well-varied diet of meaty foods like tubifex, daphnia, microworms, bloodworms, and artemia. But they should also have dried flakes, pellets and granules as the bulk of their diet.
