I was in the lfs this weekend and i came across 5 festea about 3/4 in i know how hard they r to come by so i picked them up. I have them in a 29 gallon grow out just want to keep one female and sell the rest. How long b4 they can b sexed? can a female live for life in a 125 gallon? and how long can they stay in the 29 b4 they get to aggressive?
