Haha what? My rtgg hates everything ive kept him with except for my group och thinbar myleus wich he is afraid of. He almost killed an big ol nasty paratilapia polleni male overnight. And that polleni is angry as few.
Well i cant tell that mine is small. It is almosy 40cm. Ive seen small specimens around 15cm that is really red. I think that comes down to genetics and how its taken care of.
This is mine, he was very drab when younger but as you can see he's got some nice redness to his fins. He's about 16" now. Give yours time and i'm sure it'll colour up nicely.
