That's true..but deep water zoanthids don't come in the fancy colors..that's the point being made
Of course they do. If the shallow water Zoa's were the only ones that are colored nice, then there wouldn't be any left. The shallow water stuff is the easiest to collect. Which why you can get some never seen before colors from the deepwater corals.
For example... Torch corals at 10m deep, turns brown because of too much light at 30ms deep they turn metallic green.
