In my 90g tank:
8 baby RBP's5 Danios3 Tigar Barbs1 spotted cat fish1 horned Plecho2 lobsters (one Orange one Blue)
So far the fish are getting along. I am feeding the fish frozen blood worms and frozen brine shrimp, as well as flake food and dried shrimp pellets.
I got the RBP's two weeks ago at about 5 weeks old and they are about twice the size already.
I have 11 RBP'S aprox. 6 years old around 7"-12" in a 330g liquid rubber plywood tank thier very happy with all the room. havent had a nipped fin since the tank upgrade from a 90g and a 120g to one 330g
