Purchased some Zoa frags from a local Petco today. Manager stuck her hand straight in a tank to get them out. I suggested that she might want to wash her hands thereafter and she asked "Why?" My answer was "Well, besides the fact that it's called basic hygiene many corals are poisonous and some Zoa's might even send you to the emergency room. Palytoxin is extremely potent". She replies with "Never heard of this thing Palytoxin" and walked away to ring people up at the cash registers. With such ignorant approach to saltwater coral handling I hope she never actually encounters any Palytoxin barring Zoa's in her life. Would suck to be her if she does.
