hi ive acctually benn keping fish 4 about 6 yrs. and kept guppies about 3 times but they never actally gave birth so this time im trying mollies and so my question is if a rubber maid tub would mke a good fry tank with 1 or 2 spongre filters and a heater and then my second question is if it matters if the males and females are seperated and if so when do they reach sexual maturaty and need to be speratedif so ill just float a couple smaller ones as m/f areas thanks in advance
