Try not to put your hands too close to it, even though it is not an aggressive fish it's better to be careful. They are coral safe, but they're not safe around anything that can fit into its mouth such as small fishes and invertebrates. They generally do not sting things on purpose, the spines are for defense only. The sting is not lethal unless you are allergic to the venom. If you are stung, submerge your hand in water as hot as you can stand, this will help break down the venom. Hope to help
