That is just their way of communicating with each other. They are probably sorting out who is going to be dominant (female) and who is going to be the male. Perfectly normal. Just enjoy the show!
Wow that's cool...I would have had no idea.
I have one more question...One of the Clown Fish has a cotton like white spot on it's nose. I had given him a Fresh Water Dip 3 days ago. The spot is still there ?
Brooklynella will appear as a fuzzy spot at first.
I'd suggest posting a picture or detailed description in the Disease Forum. It could be just a bump against a rock but it would be better to make sure.
