Okay so I evicted all of my angels, they got way to mean and killed off almost everything. Right now the tank currently houses 5-7 bloodfin tetra, 2-3 panda cories, and 1 cardinal tetra. This tank is understocked and I want a large peaceful tank. I am going to pick up some more pandas and tetras. I'll probably start a colony of RCS. What else should I put in?
