Cucumbers & Nudicranchs

The Berghia nudibranch is a highly specialized predator which only consumes Aiptasia anemones. It is very small and may become sucked into powerheads so all pumps should be screened. It is nocturnal and may only emerge at night. Typically multiple specimens are employed to rid an aquarium of Aiptasia, and since they feed slowly it is the eventual Nudibranch offspring which will make a noticeable impact on anemone populations. It is extremely sensitive to changes in water quality and is only recommended for expert aquarists.

Sea Hare are huge slugs with massive appetites for algae. Most species eat soft green hair algae, although spotted Hares may also eat macro algae such as Caulerpa. Sea Hares have soft bodies and may become sucked into powerheads so all pumps should be screened. It is common for Hares to bury themselves in the sand. If stressed or dying they can release an ink into the water which should be quickly removed with water changes and fresh carbon. They are extremely sensitive to changes in water quality and are only recommended for expert aquarists.The Green Sea Hare is similar to the Black Sea Hare except for color. It may be shades of olive and moss with camouflaging patterns. The long sense organs on its head resemble the ears of a rabbit. It has an internal shell but is soft on the outside. It is commonly imported from the Philippines.

Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. They require well established aquariums for both water stability and sufficient food supply.The Black Knobby cucumber is pure black with small spines along its sides. It is a useful sand stirring animal which digs down into the deeper layers of substrate. It ingests sand and digests any organic matter.

Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. They require well established aquariums for both water stability and sufficient food supply.This delightful animal is a bright sunny yellow sometimes with greenish stripes. It uses its tiny tube feet to attach itself to its environment in an area of high water flow, extending its feeding tentacles to catch tiny floating food particles from the water. If provided with enough food it may reproduce by division. It grows up to 2 inches long.Covers over all intakes are required or the cucumber may accidently become sucked inside. Like other filter-feeding cucumbers its body contains holothurin toxin. This species is unlikely to cause problems, however, because it contains only a very small amount of mild toxin. A water change and fresh carbon should be used if it is noticed a cucumber has died. Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. They require well established aquariums and addition of supplemental foods such as phytoplankton. If it is starving it may shrink in size or lose its feeding tentacles, at which point food supply should be increased.

The Sea Apple is a large, spectacularly colored filter feeding cucumber. It uses its tiny tube feet to attach itself to its environment in an area of high water flow, extending its feeding tentacles to catch tiny floating food particles from the water. It grows up to 8 inches long. Covers over all intakes are required or the cucumber may accidently become sucked inside. Like other filter-feeding cucumbers its body contains holothurin toxin. This species may poison the water if dying or harassed by its tank mates. Butterflyfish, angelfish and other animals who pick on invertebrates should never be kept with the Sea Apple. A large water change and fresh carbon should be used if it is noticed a cucumber has died. Echinoderms such as cucumbers are extremely sensitive to changes in the water quality. It requires a well established aquarium and frequent additions of supplemental phytoplankton food. If it is starving it may shrink in size or lose its feeding tentacles, at which point food supply should be increased.
