Info

Psammogorgia arbuscula,

Psammogorgia arbuscula forms bush-like colonies with thin branches and twigs and branches up to eight times.
The coral is a real eye-catcher, the branches and twigs are dark red and the expanded polyps are bright yellow.

Psammogorgia arbuscula only occurs in the tropical East Pacific of Panama, Costa Rica, Ecuador, Mexico and El Salvador.

Imports are not available.

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

Feeding
The majority of 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.
