take it from a recent msitake maker who also tried to fit 8 fish in a 2 gallon, DONT DO IT!!!! espacially with the kind of filters those tanks have. my fish died in the first week, once 4 in less than 2 hours. take everyones advice get a 10 gallon. i got a whole ten gallon kit for almost what i paid for the 2 gallon. its worth every penny :thm:
