ok i just got a new fish from petco that just died a few min ago
called petco and they said i can come in and put the 10 donation i paid for the fish against another fish they have a 1" rtc/tsn for 20 bucks how i know i would have to rehome it or get a bigger tank. but how long would it be able to live in a 100g tank before i would have to get a new tank?
