I got several new frags at the meeting and came home, acclimated them, and proceeded to put them in the tank. All was well until I put in the red and green candy cane which never closed up and was fully open with feeders out the whole time. When I sat it on the rock where I wanted it my male maroon clown bit it first then grabbed the frag plug in his mouth and shoved it off of the rock. Then my regal tang started slapping it with her tail wither her fins all spiked up. Then she just shot around the tank to try to bite and slap all of the other fish she came across. Very agitated but why? Whats different about this coral that would piss my fish off like this?
