What size tank would I need if I wanted to get, say, 5 platies? Not counting room for babies- I realize they'll probably happen. I wouldn't encourage it, but I would have a grow-out tank that I could put them in until selling or trading them or whatever.
Would they be happy with just that many in a tank? How hard are they to sex?
