Colochirus crassus
The Pink and Green Sea Cucumber is a colorful filter
feeder for home reef aquariums over 100L. 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. Feed daily with zooplankton or other liquid
invertebrate food. Like other Sea Cucumbers, Pentacta anceps has the potential
to poison an aquarium. The chances of this happening are very rare unless the
animal becomes highly stressed (for example, is accidentally sucked into an
uncovered pump intake or overflow boxes). Be sure to acclimate properly and
house with appropriate inhabitants. The Pink and Green Sea Cucumber cannot
tolerate high nitrate levels or copper-based medications.
