Kole tang

[Rmckoy]

My kole tang has been swimming these same fast vertical circles on the back of my tank for 3 weeks ,
Anyone know why ?
I tried to attach a video but this app doesn't support it

Upload video to YouTube then copy paste the link

A video would help but my yellow tang used to do something similar to what your describing b/c of its reflection

I've had a kole for a couple months now and he does all sorts of crazy swimming. He'll dart from top to bottom, loop around powerheads, do this twitchy backward dance- I was worried at first but now have decided it's just how they are.

If that is the only thing it is doing it is probably stressed.

I noticed awhile ago he does swim and clean algae as it's supposed to ,
But this same spot around the return is where he does his laps

Does it have enough room to swim freely? Bering bullied by other fish?

It's in a 75 gal
It doesn't seam to be getting bullied .
The cleaner wrasse is the only one ever close to it .
