I have a 48 gallon tank with 3 flame tetras, 3 lemon tetras, 4 rummy nose tetras, 6 neon tetras, and 1 angelfish. I was thinking i should take back my 3 lemon and 3 flame tetra and then add a bunch of rummys and neons and then add 1 or 2 more angels. i need someone to tell me if i am going to do the right thing. :help:
