Thanks for the info....Yea I will see what I can do...If I can get another 20 gallon high tank, I have a top that I could use and could set up another tank. Right Now I want my fish to be happy so I am hoping they will be fine. I really like that albino Priscella tetra as his personality is awesome, and the glo tetras are amazing as well. They haven't been nipping at one another which I guess is a good thing. If I get 2 more Priscella and 1 more glo tetra, would that be too much for this tank?
