My bettas met each other a few days ago and I fixed the tank. So they're living together again. Sprinkles is healing and looks like he got a bob haircut and is back to his normal demeanor. Blue, however, is not, he keeps swimming to where the divider slipped and pushing it. Is it safe to keep them together divided still or should Blue have his own tank? I don't want to stress him out. Also, he doesn't seem to be healing as fast as Sprinkles. I'll post some pics later to show the difference, but Blue is also at least 1/4 inch larger than Sprinkles so is it maybe because he's older?
