I am finally getting a 55 gallon tank on Friday the 5 which is tomorrow. I am so excited ;D. I also had a question. Would it be ok to put all the fish I have right now in the same tank? I have 2 mollies, 2 moons, a danio, and a rainbow shark. And about how many fish do you think would be a good idea for this size? I have seen some people put tons of fish in them and I just want to be safe.
