Sea Apples are a filter feeder invert part of the cucumber family, and should only be cared for by a seasoned or expert reef hobbyist. They require a large established reef aquarium with suitable space and a large amount of copepods and other microorganisms appropriate for filter feeding inverts. Sea Apples have tentacles that extend out into the water current to filter out their food. As the food is trapped within the tentacles it is then drawn back into the mouth. They require high flow and very stable and almost perfect water parameters. They do not tolerate sudden water parameter changes including salinity, pH, alkalinity, and nitrate changes. Caution should be taken when owning a sea apple and all pumps, intakes, and overflows should be protected to ensure the sea apple does not get sucked in. Sea Apples will release toxins (venom) that may kill fish in the aquarium when they are severely stressed or damaged. When keeping sea apples they should be fed 3 times a week a supplement of food designed for filter feeders.
