odd behavor of fish

[flrman]

I have a Reef tank with numerous fish, The yellow tang, the hippo tang, and the convict damsel for the last couple of days have been swimming in small sprints on the front glass very rapldy. I have not seen this before, is this normal? is something going on im not sure of? Any help would be appreciated.

Thanks Carl.

Its possible they are seeing their reflection, and "combatting" with it. This is probably the case if you just see a quick sprint , dash, and dance, and the fish gets all flared out. Some fish like tangs and triggers like to move, so theyll sometimes "pace" the glass.
