Sea Apple

Sea Apples are filter-feeders and have obvious rows of tube feet which they use to attach themselves to some substrate in an area of high flow.  The high flow allows them to expose their feeding tentacles to the greatest amount of passing water in order to collect suspended organic particles on which to feed.  These attractive animals remain relatively small, and a full grown animal would probably average about 4"in length.

Sea Apples prefer an established reef aquarium with room to move about, and large amounts of live rock from which it receives a majority of its food. Once it finds a favorable location, usually in a high current area, the Sea Apple will generally stay there. Protect all intakes on pumps and power heads, to eliminate any possibility of being sucked in. When the Sea Apple becomes stressed it can blow itself up to twice its size by taking on water. The species may release toxic compounds when stressed or it dies, which can kill fish and other inverts. This usually occurs when sucked into a power head or being crushed under a fallen rock.
