I have 5 male cherry barbs and am looking for some possible tankmates. Would black phantom tetras work? What about a female betta? I have a 12g marineland tank. I know its not the biggest tank but I know I have some room to work with, I just don't know which fish match up with my cherry barbs. Any other fish breed suggestions? Please no snails or shrimp though, not really my thing. Thanks in advance for the advice.
