Info

This is an azoocanthellate gorgonian that needs to be fed.

Information from Kathrin Taubert:
So far, I have the impression that it prefers stronger currents; it does not open up in calm areas.
When I turn off the current, it only takes a short time for it to retract all of its polyps, even when I feed it.

Recommendation - the coral should be kept in a species-specific tank.

Feeding
Gorgonians do not have zooxanthellae and do not live off light. Azooxanthellate gorgonians do not host symbiotic algae that produce nutrients and energy through photosynthesis.

The pumps should be switched off before feeding. In order for the gorgonian to survive in the aquarium, each individual polyp must be fed sufficiently, i.e. daily or 3-4 times a week. Without feeding, the gorgonian will not survive in the aquarium. The polyps need a certain amount of time to absorb the food (granules or dust food (Ultramarin, Cyclop Eeze) or frozen food (lobster eggs, mysis)). If shrimp and fish are present, they will try to steal the food, so it is essential to feed these cohabitants beforehand.

Newly introduced gorgonian sticks can be stimulated with a liquid food, e.g., PolypLab Polyp, to encourage the individual polyps to open. Only then can feeding be carried out.

The better the individual polyps take up the food provided, the better the growth and reproduction rates will be.

Azooxanthellate corals eat suspensions, marine snow, microplankton, and other organic matter, which is their natural food.

The gorgonian is almost always open, both during the day and at night.

These coral species live in waters with strong currents, where they attach themselves to rocks.
The flat, fan-shaped corals grow slowly and reach a size of about 50 to 80 cm.
The colonies are yellowish, beige, light orange to reddish, flat and firm, and the main branches branch off at a distance of 10 mm.
The side branches are short and thick, the main branches have a diameter of 4.5 mm, and the side branches and small branches reach 4.2 mm.

They usually form colonies and, due to the many internal and external symbionts, occupy an important position in the ecosystem.This is an azoocanthellate gorgonian that needs to be fed.

So far, I have the impression that it prefers stronger currents; it does not open up in calm areas.
When I turn off the current, it only takes a short time for it to retract all of its polyps, even when I feed it.
I have observed that it also consumes Artemia, and I additionally feed it dust food (Ultramin F and a new Ultra mixture for gorgonians).
Furthermore, every evening I dissolve half a teaspoon of Ultra Live in water and enrich it with 2 ml of Ultramin S.
