Ya, I think anything other than those thick gloves used for pruning thorny plants won't offer much protection and those thick ones probably don't offer protection from a bite. They're also so thick you can't actually do anything in the tank with them on. I think the thin gloves are probably good for people who develop rashes from the tank water but that's it. It's amazing how some corals can cut like razors.I did go and immediately wash my hand to help try to make sure there wasn’t an infection. I even had gloves on which I honestly rarely use. They were cheap, thin gloves and offered no resistance to me being cut.
