The Acalycigorgia Sea Fan is peaceful, but it should be given adequate space away from neighboring corals or anemones. Underwater epoxy is commonly used to anchor its base to a piece of live rock in the reef aquarium. It is more challenging to maintain this species, as it requires supplemental feeding several times per week. This Sea Fan is not photosynthetic and requires a low level of lighting to ward off a build-up of microalgae. It also requires a stronger water flow and the addition of iodine, calcium, strontium, and other trace elements to the water.

Because it is not photsynthetic, its survival is dependent on regular and frequent feedings of micro-plankton, live, baby brine shrimp, or foods designed for filter feeding invertebrates.
