ok, I have some questions on guppies or mollies, because Im going to start breeding them again. Last time I did, my dad turned down the heat while I was gone, and ALL of them died. He wont do it again tho, he felt bad. Alright, once my fish spawn, what do I do once the numbers get out of hand? I understand selling is sometimes available, but what if some of our stores dont buy? Can I jsut feed them to their parents occasioally? *tear tear* Or someone said to try out a non aggressive fry control fish (or something, cant remember how he said it) What kind would you recommend? And I'm going to have like a 30 - 40 gallon aquarium. I can have a 5 or 10 gallon on the side too. I'm leaning towards getting mollies right now, any other suggestions? And how old should they be before selling? Sorry for all the questions.... oh yeah... What to keep their tanks clean? Besides filter, I once had a filter in a fry tank and got some stuck in it. What kind of cleaners?
