The two had been chasing for a few days and the common clown hasn’t been allowed near the anemone since I put it in there. They don’t appear to have ripped fins or anything but I do want to be sure that they aren’t about to get crazy violent. I got up in the middle of the night (all the lights off) and peeked in my tank and they were doing this. I stayed to watch and they did it for as long as I sat there. Any suggestions or is this just them establishing dominance?
