well i was going to get a 55gal, but the 75 was cheeper and more convinient and i'm glad i got it. however, i'm not sure what else to stock it with. all i know is that i'm going to have 1m/3f snow white socolofi, 1m/3f red zebras, 8 labs. i'm not sure what else to get. i was thinking about getting a single ahli, but i'm not sure if that is a good idea. any ideas?
