There's more, but that is what I remember the most. Spiny lobsters often group upsidedown on undercut reefs. They like some current.
Unfortunately most reef fish are very easy to catch so anything edible is likely to be hard to find or small for its size.
I really prefer snorkling to scuba. Scuba has noisy fixtures, it's heavy and it's hard not to spend an extra $100 a day for all the maintenance plus training. I think it's just too complicated for what you get out of it, but that is just me. The trick to staying under is to always be blowing a small stream of air out as you hold your breath. It's the CO2 build up that makes you want to exhale and breath back in again.
I wouldn't mind trying a snuba set up if it was around. It uses a hose to an inflatable boat above the divers so there is no heavy equipment. You can stay down at 15' all day.
I'm sure there are other people on the forum who can tell you much more about diving. Snorkel is fun though and once you have the gear, it is pretty cheap to do whenever you want.
Another good fish to eat is the Dolrado, which is called Mahi Mahi in Hawaii and sometimes Dolphin Fish. It is not a reef fish though. It is very pretty when first caught then the colors fade. You can often see fishermen selling them hanging from a stick:
