Hoplolatilus cuniculus Dusky Tilefish are beautifully colored marine fish with an active disposition and a tendency to engage in burrowing behaviors. Most species found in aquariums are burrowers, creating homes beneath rocks that provide cover from predators and a safe haven for sleeping. Generally regarded as coral reef species, Tilefish are commonly found on sandy or silty substrates at the base of reef structures. They tend to hover above their lairs while hunting for food, and when they sense danger, they quickly retreat to their burrows until the threat has passed. Dusky Tilefish require a higher level of care and are not suitable for beginners. They need ample free-swimming space and good cover. Due to their deep-water origins, it is recommended to keep these fish under low to moderate lighting conditions. A sandy substrate of at least 3 inches deep is necessary to allow for digging. Providing live rock or other solid structures can help mimic the natural cover they seek in the wild. Ensure that these structures are secure to prevent collapses as burrows are created. Dusky Tilefish can grow up to 6 inches and should be housed in aquariums of 50 gallons or more. While they can be good community fish, they are often territorial toward other Tilefish. Due to their small size and relatively high activity level, they do best when fed small amounts multiple times a day. Their natural diet of plankton aligns well with common foods available to aquarists, such as mysis shrimp and other meaty morsels. The Dusky Tilefish typically displays a pale olive brown to yellow coloration but can also appear green. They are found in the Indo-West Pacific at depths of up to 300 feet.
