I have a single blue damsel in my predator/aggressive tank. Yesterday I introduce a young snowflake moray. Its about 6-8 inches long. I also have in the tank a niger triter, a lunar wrasse and a one spot fox face. Anywho, the damsel is acting weird towards the eel. It is the only one in the tank that acts like it cares about its presence. Its not being aggressive towards it but simply dusting it with its tail. Like clowns do when mating or cleaning a spot to lay eggs. I'm not at all concerned but was just curious. Is my damsel trying to say its boss or trying to claim that spot in the tank? Its not nipping at the eel, in fact, the eel bit the damsel (witch doesn't bother me at all) but didn't harm him (darn... lol,jk). Any thoughts would be cool. Thanks in advance!
