Sebastian:
As far as crabs it's left handed hermits(which can be mean sometimes), decorators, and porcelains, and pistols (not as colorfull as you may be expecting). Snails there are nassarius vibex and obsulatta(sp), but you only want the vibex. You can google for pics to identify them. There are brittle stars, usually the nano sized ones. There are also cucumbers like joe mentioned. You can also find the occasional beadlet anemone (some also call the whart anemone), or the rock anemone(not the rock flower just the rock). Both of these anemones look similar and are fully retractable. Hurting the foot on either of these species is guaranteed death. They are atlantic anemones and be a bit on the aggressive side, which just means they COULD eat a fish. I have had both of these in with clownfish and never had an issue. As for fish at this location you can go two methods, a hand dip net and you can find seargent majors and other miscellaneous damsels around the rocks. If you purchased a seine net you can find sea horses, file fish, pipe fish, lots of various gobies, most common is the gulf goby. You can also find macro algae floating and collect large pods by swishing it around in water.
