Another bit of help..
I'm guessing this is either a Damsel or a Hamlet ..
It's most likely the damselfish Beaugregory. It would be helpful to know where the photo was taken just to make sure the range is correct.
Thanks.. these were in St. John, USVI in abouit 20 feet of water. 2/8/2012
Yes, still going with the Beaugregory. It is very similar to Cocoa Damselfish, but the Beaugregory is more common and the lines on the scales are not as distinct.
Thanks. That's what I'll call it.
