Tiger Tail Cucumber (Holothuria hilla) is a marine invertebrate kept by aquarists for reef-tank cleanup, biological control of pests, or aesthetic display. Suitable for keepers with 6-12 months of experience and stable water chemistry.
Where Tiger Tail Cucumber comes from
Tiger Tail Cucumber (Holothuria hilla) is native to Indo-Pacific reef ecosystems, with wild populations distributed across coral reefs, sandy lagoons, and rocky tide pools. Captive specimens are typically wild-collected; some species are starting to be aquacultured but most Tiger Tail Cucumber sold today still comes from wild reef collection. Sustainable sourcing matters - look for vendors who can verify their collection practices, and consider aquacultured alternatives when available.
Tiger Tail Cucumber tank size and setup
Tiger Tail Cucumber requires a minimum of 55 gallons for healthy adults. The minimum is based on the species' adult size (10-12 inches), territorial range, and behavior pattern. Most Tiger Tail Cucumber sold at small juvenile size will reach full adult size within 12-24 months and the system must be sized to the adult, not the juvenile.
For a Tiger Tail Cucumber setup: mature reef tank with stable parameters, live rock for cover, sandbed substrate (1-2"), reef-grade lighting if photosynthetic, and a fully-cycled biological filter at least 6 weeks old. Newly-cycled tanks under 6 weeks crash the parameters that Tiger Tail Cucumber depends on.
Tiger Tail Cucumber requires standard reef parameters held tightly stable: Temperature: 76-80°F (24-27°C) Specific gravity: 1.025 (refractometer-measured) pH: 8.1-8.4 Alkalinity: 8-9 dKH Calcium: 420-450 ppm Magnesium: 1300-1400 ppm Ammonia + nitrite: Both 0 ppm Nitrate: Under 10 ppm Copper: 0 (lethal to invertebrates)
Tiger Tail Cucumber is sensitive to copper - never medicate the display tank with copper if Tiger Tail Cucumber is present. Stable parameters beat perfect parameters.
What Tiger Tail Cucumber eats
Tiger Tail Cucumber is a detritivore. Eats uneaten food, fish waste, and biofilm. Generally finds enough food in a stocked tank without supplemental feeding. If population thins, drop in algae wafers or sinking pellets weekly. Feed Tiger Tail Cucumber appropriately for its size + activity level. Overfeeding is the #1 cause of water-quality crashes in tanks of all sizes.
Tiger Tail Cucumber tankmates and compatibility
Tiger Tail Cucumber is generally peaceful and compatible with most reef community species. Avoid keeping with predatory fish that view inverts as food: large wrasses (especially halichoeres + thalassoma), triggerfish, pufferfish, and certain large angelfish. Multiple Tiger Tail Cucumber can share a tank but compete for food.

Tiger Tail Cucumber adult size and lifespan
Tiger Tail Cucumber reaches 10-12 inches at adulthood with a captive lifespan of 5-8 years with proper care. Many marine inverts molt periodically; provide adequate calcium and a stable parameter regime to support healthy molts.
Can you breed Tiger Tail Cucumber?
Tiger Tail Cucumber breeding in captivity ranges from straightforward (some shrimp, snails) to nearly impossible (most starfish, urchins) due to pelagic larval requirements. Captive-bred specimens are increasingly available from sustainable aquaculture facilities; check with vendors before assuming wild-caught origin.
Common Tiger Tail Cucumber diseases and problems
Tiger Tail Cucumber is sensitive to copper, ammonia spikes, low oxygen, and rapid parameter swings. NEVER use copper medications in a tank with Tiger Tail Cucumber. Symptoms of stress: reclusive behavior, color loss, refusal to feed, abnormal molting (incomplete or stuck molts). Most Tiger Tail Cucumber deaths trace back to acclimation shock or parameter mismatch - drip-acclimate over 45-60 minutes when adding to a new tank.
