Clownfish sick and wants to fight?
I've heard this time and time again, "Clowns will be clowns," but this behavior is very odd to me. I'll give you a quick summary of what has happened over the past few weeks. I recently broke down my tank last month and moved it three hours away. I had planned everything perfectly until my friend didn't show up to help me move and the live rock got stuck in a container in some cold temperatures for quite a few hours. The fish and a few pieces of live rock were put in a heated/aerated container for the duration of the trip.
I think my tank is going through a mini-cycle and that might explain why the clown is sick. I also have a male clown, firefish, yellowtail damsel, gramma and a handful of inverts. For most of the day, she seems to rest vertically at the bottom of the tank in her corner. Her mate usually stays by her side, but occasionally ventures out into the open himself. The other fish seem to be acting normally as they were before the move. The behavior that I find really odd is when the female clown actually comes out of her corner. She seems confrontational towards the yellowtail damel now. The yellowtail has always had his own territory and nobody ever really bothered him. Now, the female clown goes out of her way to invade his space and does a little "dance" in front of him. There has never actually been a fight, just a lot of fins extended and odd movements.
I'm not sure if her acting sick and lethargic has anything to do with her new found aggression, it could be totally coincidental. I'm just hoping that she snaps out of feeling sick. Oh yeah, her color is exactly the same as it was before and she eats just as much as before.
