twitch?

[buckey]

I recently bought a powder blue tang and i have noticed that she often has quick and sudden twiches. Is this normal behavior for these fish or has mine gone a little squirrly on me? If anybody has one of these fish or knows about them i would like to hear from you. thank you.

This twitching is sometimes a normal thing for any new fish..But it also could be an early sign of a larger problem(ICH).How big is the tank you put it in?? How old is this tank?? What else is in the tank besides him??

We have a 50 gallon aquarium that is approximately 4 months old. In the tank we only have one blue damsel and a picasso trigger, which she likes to pick on. She seems to be fine otherwise, just once and a while she twitches.

i have a 50 gallon , with a picasso and a yellow tang, the tang kinda rubs against the rocks, and at night, the tang gets a brownish spot on its sides.. do all of them do that?
