      Scientific Name: Istigobius decoratus
      Max. size: 13.0 cm TL (male/unsexed)
      Environment: reef-associated; marine; depth range 1 - 20 m
      Distribution: Indo-West Pacific: Red Sea to Samoa, north to Taiwan, south to Lord Howe Island.
      Morphology: Dorsal spines (total): 7; Dorsal soft rays (total): 10-11; Anal spines: 1; Anal soft rays: 9-11; Vertebrae: 26. Color highly variable. Segmented and non branching caudal rays 3 (rarely 2), branching 14 (rarely 15). Predorsal cycloid scales 7-10, trunk ctenoid. Few with no black spots on nape. Isthmus narrow, scaled forward to vertical at posterior part of preoperculum. 2 diagonal, dusky lines on operculum; an inverted U-shaped spot prominent at the distal end of upper jaw. Pectoral fin with small dusky spots; 2 longitudinal lines on pectoral base spreading onto it fin rays. Sexual dimorphism exhibited in anal, pelvic and 2nd dorsal fin.
      Biology: A common species that inhabits areas of coralline sand of clear lagoon and seaward reefs. Found singly.
      Aquarium Care: Has a temperature range of 72 - 82°F (22 - 28°C) and their natural diet consists mainly of benthic invertebrate. They are a sand sifter, picking up large mouthfuls of sand and expelling it through the gill covers, sifting out anything edible. Requires a meaty diet, i.e., enriched brine shrimp, mysis, finely chopped fish or shrimp flesh, and other various frozen carnivore foods, with one or two feedings per day. They should be housed in aquariums with a sandbed of at least two inches in depth and not housed with aggressive fishes such as groupers, dottybacks, triggerfishes or aggressive angelfishes. Small sinking enriched shrimp meal pellets are an excellent way of keeping them well fed. Little else is know about this species as its not often seen in the trade. One per tank.

      I have one of these, neat little fish, has dug caves all over my tank and is always changing the way the sand drifts, adds a nice effect to the tank.
