scribbled rabbitfish dorsal fins are flicking...

[scuba_steve]

I just brought home a scribbled rabbitfish, and since I have put him in the tank, he swims and his dorsal fins flick. Kind of like the fins are spazzing out.

Is this normal, or is something wrong? I drip acclimate all my fish and he seems fine except for the dorsal fin. He's eating and active.

All water parameters are fine.

They do this as a warning to other fish at times. Mine would tilt his head down and hold his fins erect when he felt threatend. Kind of cool. I'm not sure if yours is doing the same thing, but if he is eating I would not worry to much.
