I just bought 2 boesemani rainbows 2 days ago and put them in my 10 gallon tank, which is populated with brilliant rasboras and celestial pearl danios. At least 1 of the rainbows is a male. The other 1 is pretty colorful too, but not as much as the 1st, and I don't know enough about them to accurately sex it. Anyway, the rainbows, the 1st especially, immediately started chasing the danios. I was worried because the danios are so small, but this behavior stopped within minutes and I haven't seen it since. Later that night, I notice one of the rainbows chasing my biggest rasbora. It's almost as big as the rainbow. The funny thing is that it never tried to nip at the rasbora. It just kept trying to get underneath it. He'd get underneath it so close they were touching and he would kinda shimmy. Then the next day, I noticed the 2 rainbows fighting maybe, except again, neither one nipped or anything. They kept trying to ram into the side of each other. Like they were trying to roll the other 1 over. Besides these instances, everybody gets along fine most of the time. What are these behaviors? Should I worry? Are they just temporary due to the environment?
