Blue polyped gorgonian

Thats too bad Tony.

This confused me a bit.

(Telling apart photosynthetic versus non-photosynthetic is supposeldy fairly simple - zooxanthellae is brown, so the polyps are brown

Photo is brown, so if the gorg. polyps are brown it should be photo? And if they are say blue it is non-photo? Is that what you meant?

Yeah, basically. On a photosynthetic gorgonian, the polyps themselves will be tan or brown (although the flesh in between polyps may be a different colour). So if the polyps are white or brightly coloured, then it's probably a filter-feeder and not photosynthetic.

But some people seem to do OK at the non-photosynthetic ones ... I'm hoping to try again some day but just not in this tank.
