Ha! I normally draw the line at giving medical advice for humans (see disclaimer in my tagline below).
Was it a puncture or a slash? If the latter, less of an issue I think. Still, aquariums have a variety of nasty bacteria in them.
Side story: back in the 1980's, I was the head diver at a public aquarium. One of my divers got slashed by a 8' green moray while he was CARRYING IT during a dive show. He finished the show with his hand tucked under his arm. When he came out, I couldn't stop the bleeding and so I drove him to the hospital instead of calling an ambulance (because I figured it was faster), but still, that was stupid on my part. He recovered with no loss of function, but with 30+ stitches so I guess you'll be o.k. (grin).
Jewel morays sure are nasty critters....seriously though, any sign of infection, see a doctor!
