Identifying Rainfish

[Adohan]

Hi, bought these rainbow fish from local store, they called them yellow tail rainbows but can find that name online. Anyone got a suggestion for what they really are?

Hi and welcome to the forum

Melanotaenia boesemani

Make sure they get plenty of plant matter in their diet. At least half of their diet should be aquatic plants and algae, vege flakes, etc.

The following link has all the known rainbowfish from Australia and New Guinea.
