I have a 40B that is basically empty of Fauna. Right now there are 3 Tiger Nerites and 5 Oto Cats in the tank and that's it. I've been thinking for weeks about what to put in the tank. My LFS just got some gorgeous Fire and Blue Gouramis. I was wondering if I could keep 10 or so of them in this tank without issues? Will both species play nice together? I know some Gouramis can be semi-aggressive and become a problem. I also know some of them get big and a 40B isn't sufficient. From what I can find both of those species appear to be dwarf Gouramis which stay smaller. Any info would be greatly appreciated. I've always loved Gouramis but have never kept any.
