Is there any paint that is reef-safe? I know it's a weird question but I have a small tank that my son wants me to make into a reef tank for him. I want to let him take care of the tank on his own but don't want to put anything in there he can kill, maybe a few damsels. I want to paint all of my old dead sps's so that they look real and he then thinks he has "corals" in his tank. Just a thought....any help will be appreciated. Thanks.
