Help ID this fish please. Damsel, Porgy, something else?

Photographed by the rocks at Bill Bagg's Park, Key Biscayne, FL July 7th. near surface, depth there was about 4-6ft.  Body lenth 4-5 in. I thought some kind of Damsel or reef fish because of head and mouth looking kind of small for the body. Plus it seemed to be behaving similarly to other damselfish and Sargeant Majors that also inhabit those rocks. But then again the overall body shape, and in particular the tail and fin shapes also look like a silver porgy. However, couldn't find anything in either family that came close to this colors. All three pics are the same fish. Most of the time it was plain very light gray, but it would some times display that brown and white poka dot pattern. Does anyone know what it is?  Thanks for the help.

UPDATE: WELL, I WAS SNORKLING IN THE PARK AGAIN THE NEXT DAY AND SAW SOME BIGGER SPECIMENS OF THIS FISH. I'm now pretty sure these are juvenile CHUBs. Is this correct???

Yes...I agree it is a chub -

Yes...I agree it is a chub - I have the REEF Fish Humann interactive DVD...it shows several pictures of the same fish - You were right, it is a juvenile.

Juvenile chubs seem right

These do look like juvenile chubs (Kyphosus sp.) to me.  I've never seen one with spots, however.
