gotchya! so only people eaters show white streaks when the polyp is closed ?
You are not ever really going to get an adequate answer here... As it seems there are exceptions to every rule, of the "naming fad"...
"People Eaters' are just a silly name someone came up with for marketing purposes of
Zoanthus gigantus. You said yourself, you would like to "collect them all..." I will sum it up for you, "True People Eaters" are the ones people are sellling as "True People Eaters" Strictly for marketing purposes, they are all
Zoanthus gigantus.
Think of it in terms of
Zoanthus gigantus, and you will be all set. There are literally thousands to millions of morphs of
Zoanthus gigantus. Some of which have not even been discovered yet I am sure.
Here is a nice little real life senario that i hope drives the point home for you. Last week I picked up a colony of 350 polyps of
Zoanthus gigantus at my LFS. I knew they had potential so I said "bag em up." The $30 price tag was enough to make up my mind for me. Upon arriving home and placing the polyps under good lighting, they opened. The polyps are all bright red, with a neon green mouth. My lfs did not call them "people eaters" as this description is no where in an id book, they called them zoanthids.
