Probably one of the most popular of the rainbowfish, the Boeseman's Rainbowfish (Melanotaenia boesemani) is quite colorful. While only silver in color as juveniles, these fish become quite stunning as adults with a brilliant orange-red back half and a silvery-gold front half. This rainbow also features violet-blue vertical stripes on their front half, as well. Finnage ranges in coloration, usually tipped in white. As with most rainbowfish, the Boesemani has a double dorsal fin.

Rainbow fish make a great additions to a community tank. Their sleek, oblong bodies are made for speed, and they constantly make laps back and forth through the aquarium. Many species grow to 3 to 4 inches in length and a small group of these fish can add extraordinary color to your tank. While juveniles may have a relatively drab appearance, they truly live up to their name as they mature. Males are especially colorful in most species, developing vibrant yellow, orange, red, blue and green shades, some with stripes or bars. Both males and females should be kept in the aquarium so males retain their vibrant hues. Rainbows are schooling fish, and it is best to keep them in groups of at least four so they feel secure and stay in the open.

New species and variations of Rainbowfish are being discovered and imported for aquarium use each year as they gain in popularity. The largest and most well-known genus is Melanotaenia, and species from genus Pseudomugil are also frequently offered. Other less common species may also be seen in our tanks from time to time. Most Rainbowfish originate in lakes, streams and rivers of Australia, Southeast Asia, and other islands in the region.

Rainbows can be kept with a wide variety of community tank mates like tetras, danios, rasboras, others Rainbows, dwarf cichlids and similar fish. They are not picky eaters and will generally accept flakes, pellets and a range of frozen foods like mysis, brine shrimp and other similar items. They will not bother plants and are ideal for planted aquariums. A long aquarium is best to give them plenty of distance to swim back and forth in the tank.

just a cool fish with cool colors

Very good handling


The fish arrived healthy and in minimal distress. Given they had a long trip behind them thats remarkable. The packaging was superb, delivery well executed.

Overall an excellent event.

Arrived in great shape


These are such neat looking fish and they get along well with the rest of the fish.



The fish arrived on time, healthy and as described. Their color began to develop quickly and they are thriving with my 4 severum. They definitely keep their tankmates calm.



Arrived quickly and were already colored up. Very pleased. Need a few more in another week or so!



These fish aren't just beautiful, they get along really well with my other fish.
