My one female gave birth today while we were working. There are probably around 6 or 7 fry that have been swimming around the tank, hiding in the plants and in the crevices in the gravel. We both have enjoyed this very much, even though it's only been a couple hours since we noticed. I am going to either get a breeder box or set up my old 5 gallon (somewhere

) for the other female who will likely drop hers soon.
The one female that was nipped by the guppy seems to have developed a little fin rot in her left pectoral. Would it be okay to medicate with Maracyn, with fry in the tank? I don't want it to get any worse, so I think it would be good to take care of this before it gets worse.
