What do sea fans do?
Sea fans use their polyps to trap small food particles, such as phytoplankton and bacteria. The sea fan usually grows so that it is best oriented for the prevailing water current to flow over the polyps for food to be easily trapped. The polyps are connected by fleshy tissue.
Are sea fans endangered?
How big do sea fans get?
There are about 500 species of Gorgonia, and they differ markedly in their branching patterns. All, however, grow to approximately 60 cm (2 feet) in height. Sea fans are found in the shallow waters of all oceans, but they are especially abundant along the Atlantic coasts of Florida, Bermuda, and the West Indies.
How fast do sea fans grow?
They seem to be very healthy with polyp extension and good color but they have only grown 1/8 of an inch in 6 months. Other reef keepers have had the same experience. In the wild, these sea fans grow very fast. However, in captivity they grow very slowly.
What class do sea fans belong to?
Anthozoa is a class of marine invertebrates which includes the sea anemones, stony corals and soft corals. Adult anthozoans are almost all attached to the seabed, while their larvae can disperse as part of the plankton.

Do gorgonians like high flow?
Gorgonians tend to live in moderate-to-high flow areas on the reef. It will not be a surprise to you then, to conclude that they will do best, in the home aquarium, in moderate-to-high water flow areas.
Where do sea fans live?
The Common Sea Fan can be found in patches of reefs and outer areas of the reefs typically in water depths up to 30 meters, and they tend to thrive in areas where the water flow is at a constant speed. The speed of the water is important due to the fact that all sea fans are filter feeders.
Can you frag gorgonian?
How do you take care of a gorgonian?

Can gorgonians sting?
Like the majority of soft corals, Gorgonian corals are seahorse safe meaning they will not sting or harm your seahorses.

Corals also eat by catching tiny floating animals called zooplankton. At night, coral polyps come out of their skeletons to feed, stretching their long, stinging tentacles to capture critters that are floating by. Prey are pulled into the polyps’ mouths and digested in their stomachs.

3800 gph to 5800 gph depending on surge in a 125 gallon tank. Here’s the part that I find confusing: “they need strong flow that does not bend their polyps”.

While most if not all gorgonians rely upon phytoplankton and tiny zooplankton for their food, a few are additionally capable of harboring zooxanthellae.
