My bettas have just moved into their new hexagon divided tank, complete with a black light for warmth and floating plants. I don't have much stuff at the bottom for them to hide in, because I don't want to crowd them. They have never been so close to each other and they now spend a great deal of time flaring at each other and swimming aggressively. I just wonder if tehy will ever calm down and I'm afraid they will hurt themselves somehow. I guess I can get more plants, but I don't know what else to do. I live in an RV and space is at a premium. Any suggestions that I might be able to actually do? Getting six 10 gallon tanks is not in the cards.
