The Yellow Sea Cucumber is an interesting, unique addition to a reef tank. They are a relatively small species of cucumber and are mustard yellow in color, giving them their common name. Their body is long and somewhat reminiscent of a slug, and covered with spiked protrusions. They have branchlike appendages that are used for filter feeding.
They should only be added to well established reef tanks with live rock that don't have any fish that will eat invertebrates. A group may spawn in the home aquarium or one individual may occasionally split into two.
Cucumbers should be supplemented with zoo or phyto plankton. They can release toxins if stressed out or upon death, so care should be taken to avoid stress and also to immediately remove any that have died.
