ClownFish Twitch!

[edizzle]

I just bought 2 new clownfish for my 29g tank and some times they twitch. The twitching looks like an electric shock is going through them. It dosent happen all the time but it happens enough to notice. Why are they doing this?

clownfish use this alot, its not always a show of submission, its also a warning to other fish to stay back, the female will also do it, its normal and nothing to worry about all my maroons do it to my large hermitt crab
