well I have 2 "5 gallon tank setups" running right now. But the room provided isn't enough. My platies and guppies bred and now I have over 20 fry. Then a month later my guppy had more. She ate almost all of them exsept three so I put them in the breeders net. And now my platy is pregnant all over again. Should I get a 20 gallon tank and a divider seperating sexes. And keep one five gallon running for the pregnant fish? Is this a good idea. Do you have any suggestions?
