Yeah, I get that. Coral Crouchers are venomous. The venom is not that bad though. But I get that you're nervous, the fish shouldn't dart around and willingly sting you. It's more to prevent it from being eaten. I QT'd a foxface in a small tank, and even he didn't stab me with his venomous spines even if I put my hand in to adjust things.
But hey, if it's not something you wanna deal with or are interested in then don't get it

I personally just think they're really cool, and it's funny these little fat gumdrops are venomous lol
