The yellow tail
snappers on the left swam right past my face. Their yellow and
silver markings are very distinctive. They are about 12"
long. 
The Gray Angelfish to the right is about 12" long, and fairly common on the coral reefs of Belize, along with the similar looking French Angelfish.
The very beautiful Queen Angelfish to the left is about 12". long.
The Blue Parrotfish to the right is fun to watch, with it parrot-like beak and its habit of pecking at the coral. Size 15". Some cousins of this fish have very pretty rainbow coloration.
The Squirrelfish to the left is a very distinctive reddish fish. They are quite shy and generally hid when we approached. This one is about 9" long.
The Jewfish to the right is about 2' long, small for the biggest of the groupers. These fish can grow to 8', and are not particularly afraid of divers.
The greenish-blue fish on the left is resting on a rock, I surprised him on a night dive. I think its a Parrotfish.
The Blue Tang on the right is a very pretty and distinctive fish. I found this one alone, but they often travel in schools.
The pretty blue fish on the left are typical of small groups we saw frequently.
