I caught this guy attacking my Conch, I never knew Conchs could jump! Conch leaped a good 6 inches away from this guy! I grabbed him and threw him in the sump.

Looks like a caribbean green stripe hermit crab

Looks like Clibanarius vittatus (thinstripe hermit crab). These consume algae and detritus but have been known to attack other invertebrates.
