Non-photosynthetic gorgonians - ID and particular care

[dendro982]

Got a new toy - probably non-photosynthetic gorgonian, may be you know what is it and its particular requirements, if you keep it - share experience.



The left one, compare size with Swiftia kofoidi on the right. And swiftia, in turn, with red finger gorgonian, likely Diodogorgia nodulifera, but wide form:



Was sold as Red whip gorgonian. Thin red gorgonian with transparent white polyps. Branches are ~1mm thick. Polyps are mostly on the sides of the branches:

Not like of the blue gorgonian with fine polyps, likely Guaiagorgia, where the polyps are covering all circumference of the branch (otherwise comparable by size and branching)):


Wide polyps remind chili coral polyps: red collar under the tentacles:


Chili coral, for comparison:


The closes thing, I found so far, is Leptogorgia punicea http://www.dnr.sc.gov/marine/sertc/o...ia_punicea.htm
"open pinnate branching and prominent calyces which are in double rows on two sides of the branches." "height of less than 10 cm, and the branches are 1mm wide exclusive of calyces."

The similar looking are Leptogorgia miniata and Lophogorgia ruberrima, but on photos they are covered by polyps everywhere, not just on sides.
Recognition for L. miniata: "Small openly pinnate branching colonies. Commonly branches in a single plane, but can be somewhat bushy. Low, blunt calyces in single rows along the two edges of outer branches" http://www.bio.georgiasouthern.edu/g...ta&filaindex=4

ID, tips, experience - anything.

So far no problems with feeding of any of them, except the RIP damaged blueberry gorgonian. Just mouth-sized zooplankton few to several times daily, and skimmer and micron sock filtration for a water quality.

More troubles - in lighted tank - with algae (bryopsis), red slime on the branches, in unlit tank - strands of what looks like transparent bacterial cover. Some of these gorgonians are prone to one, other - to another.
Swiftia stands out so far as the most resistant to anything.
