I have a 29 gallon tank and only had a handful of sunburst platy's in it, now they won't stop reproducing! Right now I have 2 "teenage" platy's and I just noticed 5 more babies. At this rate I am going to have way too many fish in this tank. Any advice on how to keep them from having more, or what to do with them. I really didn't want to start up another tank.
