I added a saddleback butterfly yesterday, and my tang (and a smaller blue damsel) were overly aggressive. He got chewed up a bit, and almost died last night, before I could get him back out, but I kept him moving in a breeder tank, floating in the main.
I probably can't return him to the LFS
, as he's got a couple good bites out of his rear fins, so in case he survives, I need to somehow acclimate my tang to this guy.
I could take the tang out into a separate tank for a few weeks, which would eliminate some of his territorial behavior, but he's nearly impossible to catch.
Has anyone had any luck calming aggression using tank dividers, or the bigger isolation net setups?
It seems if I can keep him going for awhile, in plain view of the tang (and damsel, which I'm still not sure was involved with the attack), they might calm down a bit around him.
