Elephant-nosed Cichlid (Nimbochromis linni)

Are you sure of the ID? I would expect a mature male to have a very differently shaped nose.

@gentle lemur positive. Plus, these animals are not mature yet. Unfortunately, most captive-bred African cichlids in South-east Asia are often soaked in hormones to induce strong colours before being sold. There, the colours fade over time. It's why I stopped purchasing captive-bred adults here as I have spent way too much on surplus females without meaning to...

@BucerosKeeper OK, now I understand: thank you for the explanation. What a deplorable practice!
