Need help with possible coral sting...

[Carandiru]

Do be careful with Zoa's - I stay away from them from now on for they are extremely risky.

Some Zoa's are fine, some are not - there are no distinct features of various Zoas that can tell you whether or not it is capable of a lethal palytoxin dose.

Simple touching, splashing of water in the eye or mouth, or "steam" if your cleaning will definitely tell you - but that's something you never want to find out.

Palytoxin is the worlds second deadliest poison - I was a little surprised myself to find this out after the fact of purchasing a zoa.
