Here are some more pics of the emperor and nile perch as requested. The nile perch will go from dull grey to awesome gold and black marble in seconds when he gets excited.
I don't know of any right now. I bought him from Wes at Rare fish, you might want to talk to him. The nile perch is skinny right now because I am trying to get him off of feeders and he is being stubborn. So far it's been a little over one week. Hopefully the new Emperor will get him to eat the frozen smelt and shrimp.
