So, I just picked up a 150 gallon tank. It currently houses 1 16" pike cichlid, 1 14" common pleco, 1 4" demasoni, 1 4" yellow lab, 4" rusty cichlid, 1 6-7" male convict, and 1 4" roseline barb. These are the fish that I brought over from my 55 gallon with the exception of the barb. I want to know what fish you guys think I could add to this tank. It feels pretty empty now. If need be I can move the barb over to another more peaceful tank to accomodate some more aggressive fish. Any suggestions would be greatly appreciated.
