The Tiger Sea Cucumber is one of nature's more exotic detritus eaters. With its brown body spotted with white and dressed in numerous spiny papillae, it is also a visually stunning addition to the home aquarium. Since it is a very adept and agile scavenger, the Tiger Sea Cucumber can clean detritus from beneath rockwork and difficult-to-clean tight corners.
In general, keep only 3 inches of worm for every 80L of aquarium water. For best care, the Tiger Sea Cucumber should be kept in larger systems with thick sand beds and rocky caves for shelter. The natural diet of the Tiger Sea Cucumber consists of diatoms, microalgae, bacteria, meaty foods, and other detritus. Interestingly, the Tiger Sea Cucumber is one of the few species that attaches its lower body to the inside of its shelter and only extends its anterior half when searching for food.
Like other Sea Cucumbers, Holothuria sp. has 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. The Sea Cucumber cannot tolerate high nitrate levels or copper-based medications.
