Thank you, Jens! Will do.
Do you know, by any chance, is the blue with fine polyps the Guaiagorgia, as I thought?
Do you have the small-polyped red with yellow polyps gorgonian, how is it, comparative to the others?
And red finger gorgonian, Diodogorgia nodulifera, ID question:
I have 4 different kinds of it, 2 vertical and 2 - wide, tree shaped.
1. I thought, that the wide one is Siphonogorgia mutabilis, based on this description
http://www.seewasserlexikon.de/weich..._mutabilis.htm , but later found, that siphonogorgia hasn't the central core:
http://www.hawaii.edu/coral/CoralIDAmericanSamoa.pdf , and mine has one, not too rigid, although.
2. Two vertical ones differ by shape:
One (on the right) is what is commonly shown as red (or yellow - the shape is the same) finger gorgonian:
Solid dark red color, hint on darker base of polyps.
Another (at the front) is different, by shape, and color - plain light red with dark base of polyps:
3. The thinner wide ones differ too: one is fluffier, higher density of the polyps, and the tentacles are very long and curved:
comparing to all the others. This is the plain wide one:
Could they be the different species, or just variation within Diodogorgia?
Food:
The food, you are giving to Elicella and other small-polyped gorgonians, is it Faun Marin and Oyster eggs-like based (I mean, high end specialized one)?
I'm giving readily available frozen rotifers and cyclops, and dried ZoPlan, but can't be sure that all of that is of saltwater origin.
And OOT question:
one of my orange scleronephthyas started to lose color (during intense growth/restoration, after being closed for some time).
Are you giving some additional food with pigments or pigment additives for yours?
