Always wash your hands thoroughly after handling them. It is important to wear gloves, a mask, and eye protection when fragging them.
How do you get rid of palytoxin?
Palytoxin can be inactivated by household bleach (sodium hypochlorite). Regular (‘standard’) household bleach is typically sold at a concentration of 5% sodium hypochlorite. This should be used (i.e. standard, unscented household bleach) and not the gel-type/thick household bleach, when preparing a bleach solution.
Does pulsing Xenia palytoxin?
there is NO palytoxin in Xenia! You are perfectly safe if you happen to have this pulsating monster overgrowing your reef tank. But, please, do be mindful of any Palythoa that might be growing nearby, as that one can cause you quite a bit of trouble.
How is palytoxin treated?
There is no antidote for palytoxin. Only the symptoms can be alleviated. Animal studies have shown that vasodilators, such as papaverine and isosorbide dinitrate, can be used as antidotes. The animal experiments only showed benefit if the antidotes were injected into the heart immediately following exposure.
Are all ZOAS poisonous?
They’re not all toxic, however it is best practice to assume they are all toxic because discerning the difference species is super difficult, so assume everything zoanthid wise is toxic and just handle with care! Paly toxin is highly toxic so don’t handle them with open wounds or rub your eyes in between handling them!
Is the palytoxin in Palythoa toxica poisonous?
P. toxica contains palytoxin, one of the most poisonous substances known. This zoanthid is not the only member of its genus to contain the toxin; that distinction is shared by P. tuberculosa. The latter species has a seasonal cycle, varying in toxicity at different times of year, whereas P. toxica is equally toxic all year round.

Is it dangerous to eat a Palythoa zoanthid?
Palytoxin from Palythoa zoanthids is really, REALLY dangerous.
