why does it matter if they are common/or sought after if you get them or not?? i think they look cool. sounds like a decent deal.
if you thought they were cool, but really common, would you not get them?
i think the big thing with those protopalys/zoa gigantus polyps that look like that in the LFS, is they are almost never truely brown. they will always color up into something cool given the right light.
