Common name:

Axelrodi Rainbow

    , Axelrod’s Rainbow, Lake Tebera Rainbow

Distribution

Oceania: 

    known mainly from the Lake Tebera basin in the Southern Highlands of Papua New Guinea.

General Body Form:They are shaped almost like an American football with fins on the back side! They have the typical rainbowfish big eyes and forked mouth.

Coloration:Females are rather dull in just silvery coloring. Males are more vibrantly colored. They blue and purple like coloring on their backs, which mixes with a silvery underside. Their fins are like a transparent yellow color.

Maintenance:These fish like most rainbows, like to have a planted tank, but still have wide open spaces to freely swim. Something that might help their coloring is exposing them to actual sunlight. It has also triggered spawning for some.

Diet:Axelrodis are omnivores, and need a variety to maintain optimal health. In the wild, algae makes up a large part of their diet, so you might want to feed them some algae wafers sometimes.

 

Biotope:Inhabits highland lakes and streams.

Breeding:These fish are not hard to breed, but keeping the fry alive is difficult. When Axelrodis mate, the male vigorously and aggressively chases the female until she deposits eggs on a plant. When the fry are hatched, it is important to keep the tank from having any fast water chemistry changes.

Diseases:Most Rainbows are prone to skin flukes, parasitic infestations (protozoa, worms, etc.), ichthyobodo infection, parasitic infestations (protozoa, worms, etc.), bacterial infections (general), and bacterial diseases
