yes you don't want coral juices anywhere near your eyes and face :P
the stuff zoas and palys produce goes beyond simple irritation.
forceps are still a good idea. I'm not saying be a sissy girl and never use your hands lmao (you'll want to use hands to move larger rocks around more carefully) but for simple stuff like spot feeding, and frag placing, it's best to have forceps around. very nice for getting small pieces of stuff out, etc.
You can get lucky for many years, but you might also one random day get stung by something you could have done without.
