The colorful boesemani male has become a favorite among rainbow fans. Starting at the tail, a deep red-orange color grades into an iridescent purple-blue as it get closer to the head. The striking colors can be enhanced by providing a dark substrate, like black pebbles or gravel. A minimum 30 gallon planted tank is recommended to keep a school of one male and 5-6 females, easy to identify by their less colorful bodies. Mixed them with danios, rasboras, gouramis, livebearers and small plecos. On bigger tanks (e.a. 70 gallons) they can be introduced safely to larger non-aggressive fish like discus and angelfish.
The males tend to be aggressive toward their own species, so keeping one male per medium-size tanks is preferable. These peaceful rainbows enjoy swimming, and are excellent jumpers, a tight cover should be used to avoid unpleasant surprises. Rainbows have voracious appetites, and large matching mouth, however their narrow throats can get obstruct easily, causing them to choke, avoid feeding them big pieces of food, specially large-size pellets. Omnivores, rainbows need a mixed diet of prepared flakes, frozen, and live foods to maintain them healthy.
When breeding males can tear fins and damage scales, so it’s best to have several females per male. Fungus and Childonella can appear, due to stress, so look closely for any symptoms of disease during and after spawning. Make sure you give them a suitable spawning mop or plant like Java ferns and have a fry raising tank ready after the egg are attached, since chances are the will eat the eggs. The fry hatch after six or seven days. The baby fish can be first fed with liquid fry food or infusoria, and as they grow, you can start to add newly hatched brine shrimp.
