Candy Sea Cucumber also known as the Red Sea Cucumber or Pentacta anceps are interesting filter feeders which will find a spot in good flow, fan out its feeding tentacles and filter the water for food.

The Candy Cucumber is a colorful filter feeder for reef aquariums. Rows of pink knobby thorns run lengthwise along its green and yellow body. Like Sea Apples, striking yellow and pink tentacles extend during feeding. Unlike most other sea cucumbers this animal normally stays stationary, when it finds a suitable location in the aquarium with the proper flow. This species of Sea Cucumber feed by pulling small particulates from the water column, which stick to the hair-like appendages off of its plume. The particulates are then moved to the mouth and ingested.

Feed daily with zooplankton or other liquid invertebrate food. Like other Sea Cucumbers, Candy Cucumbers have the potential to poison an aquarium. The chances of this happening are very rare unless the animal is accidentally sucked into an uncovered pump intake or overflow boxes. Be sure to acclimate properly and house with appropriate inhabitants. The drip-acclimation method is recommended to minimize exposure to fluctuating water parameters.

Candy Sea Cucumber cannot tolerate high nitrate levels or copper-based medications.
