Platies? Give whom more room to live together? Me confuzzled..
I had one of my females jump the divider into another female's space the other day. My tank is set up with older bettas who are quite large, so they couldn't get through the 1/4 inch gap at the top. Well, needed to toss in one of my new breeding girls in there for a day or two until the new heaters came in... lets just say she is small at 3 months and was able to get over into my older female, Anya's, side. Scared me silly as Anya is very aggressive and over twice Lemondrop's size. Luckily I caught it within a minute as my daughter was watching them and saw what had happened.
Needless to say, Lemondrop is in a kritter keeper now until I get the new breeding barracks set up this week.
It can easily take a while before the fighting begins, but both males are very uncomfortable and stressed (as shown by them staying away from one another), I really wouldn't recommend "experimenting" with that again.
