If you were trying to prop zoanthids as quickly as possible what would the optimum number of polyps per frag. I find that if there is only 3 on a frag it grows slowly at first. But a huge colony can only grow on the edges and is slow as well. So what size is juuuust right?

OK i bought some live rock and when i put it in i found i had gotten a really dark purple zoa with it. Strange thing is is it doesnt like light. it only opens at night and when the lights come on he closes up. It has also moved to the underside of the rock twice. LOL might be crazy idk. has me...
