(deep movie announcer voice)
Just when you thought it was safe to go back in the water....
Oh my god... I lightly bumped a zoa... (womans horrific scream)
Just don't lick your hands after taking a band saw to them to cut the chunk in half and you should will be just fine..
Common contact in the water is not a problem at all..
As always just wash your hands after being in the tank and all is fine..
Its not like a scary monster living right under your bed waiting to pounce at any time..
The toxicity problems are few and far between.. Like .001% of people if that with zoas/palys ever have problems..
