I am keeping 4 female bettas in a 10 gallon tank tank. During the first couple of days, they were fighting and going at it. Then they had gotten used to each other and only glared a little at each other but didn't give chase. Unfortunately, my bettas have now seem to get stuck in an equilibrium where they constantly just hide or rest. The largest one hides behind the filter and the small one among the plastic plants. The other two don't hide all the time but they do like to rest and hide occassionally as well, so my tank seems very boring at times. Are the bettas just bored? I've been thinking of ways I might try to get them to be more energetic like throw in a snail or some shrimp..
