in the beginning i was buying meds left and right to keep fish healthy. and just tossing what was left if i needed a new one.
what i have done now as someone suggested if its a "cheap" or easy to breed fish i just toss it.
BUT now before i buy meds, i go ahead and use whats left in each tank, even if no one is sick. it "seems" that i have not had as many sick fish either. i dont know if this is the case. but it seems to be working for me, i will only get one sick now IF that as opposed to 3 or 5 like before.
