Pink and Yellow Cucumbers (Pentacta anceps, also known as Spiny Cucumbers) are safe, attractive additions to reef aquariums. Their bodies are greenish-yellow in color with five columns of bright pink 'thorns' running the length of the cucumber. The retractable feeding tentacles are bright yellow with pink tips.
While some sea cucumbers are "sand-sifters" or "sand-moppers", most are filter feeders. In the aquarium trade, these are typically from the genuses Pentacta, Colochirus, and Pseudocolochirus, among others. They extend frilly feeding tentacles into the water to catch free-floating planktonic foods and pull these food items into their mouth to feed. The cucumber can be target-fed with various filter-feeder foods at least 2-3 times a week when these tentacles are extended. Most also have very strong tubed feet that they use to attach themselves onto rockwork or the sides of an aquarium. If the cucumber is moved, these tubed feet may be left behind but will grow back with time.
Sea cucumbers can be harmed if they are trapped or pulled into filter intakes or overflows. Some fish may also pick at their bodies or feeding tentacles so tanks and tankmates should be chosen with care. If a cucumber is stressed, they may expel their internal organs as a stress response. As long as the cucumber is healthy otherwise and the cause of the stress is removed, these organs can grow back and the cucumber can survive. Most cucumbers also produce "holothurin toxins". These toxins can range from a mild irritant to deadly to aquarium residents. Always choose cucumbers and tankmates with care and monitor any stress to the cucumber.
