Lions, triggers and ......... Rabbits????? OH MY????? Wait thats not right.
Its fairly easy to know what to NOT touch in fish though. Tangs, rabbit fish, triggers, some puffers, etc. etc.
I pick up my triggerfish whenever I need to. He's pretty tame, but if there's food present, he bites. On dives we use to wear gloves, but stopped when it was pointed out that you shouldn't touch most coral anyway and a gloved hand was harder on a fish's slime coat than a bare hand is. Same with coral. We use to pet groopers and morays in the wild.
