Not Reef Tank Suitable
Likely Fish-Only Tank Suitable
Range: Indo-West Pacific Ocean: East Africa to Society Islands, north to Southern Japan, and south to Australia.
Size: 4 inches (10 cm)
Natural Environment: Inhabits bottom sandy and muddy areas in near shore lagoons and reef channels at depths between about 3 - 50 feet (1 - 15 m) where it feeds mainly at night on small fishes and crustaceans.
General Husbandry: Rarely seen in the trade, having a mottled red and white coloration on its body and fins.
Best maintained in aquariums with minimum water currents, as this is an inactive species that stay in one place on the bottom substrate while waiting for a meal to come close enough to be captured/engulfed and eaten. Aquarium environment should have some rockwork and caves to sit on or be near enough to give the species the feeling of blending into the surroundings while waiting for dinner. Tankmates must be peaceful so as not to nip its large fins, and large enough not to be eaten.
As to diet, these fish are carnivores and require a diet high in protein and amino acids (lipids/fats). Products such as marine fish and crustacean flesh, clams, and other marine meaty foods should make up the majority of their diet.
As to live foods, occasional small live mollies and/or guppies can provide for that natural feeding excitement found in the wild should live marine fish not be available. Nevertheless, feeding small freshwater live fish should be considered a special treat and not become a steady diet since they lack the fatty acids that marine fish need to stay healthy.
Also, keep in mind that feeder goldfish, which cannot survive but a few minutes in seawater, also carry many different bacteria, fungi, and protozoa that can cause parasitic and infectious diseases. Furthermore, feeder goldfish can also cause blockage in the digestive track and/or kidney along with liver damage due to fatty degeneration in the consuming fish. And this will ultimately lead to the consumer’s death. In fact, fatty liver degeneration is a common cause of death in cases where marine fish are fed a diet that primarily consists of goldfish (as with Lionfish for example). Also, its possible the large air bladder in the goldfish can upset the internal balance in this fish, sometimes causing it to float at the surface, possibly killing it.
Non-living foodstuffs can be suspended/impaled on a long thin stick and dangled within range to entice feeding.
Because these are sedentary fish, their metabolism is quite low and three or four feedings per week should suffice nicely.
May be difficult to feed in the early days in the aquarium and if so, (if live marine fish are not available) live glass/grass shrimp and/or small crabs, e.g., fiddler crabs may be needed to sustain the fish.
