Diese Art kommt unseres Wissens nie in den Aquaristikhandel. Die unter diesem Namen verkauften Tiere sind in Wirklichkeit stets Colomesus asellus.
C. psittacus hat im Gegensatz zu C. asellus 6 Querstreifen statt 5, woran die beiden Arten am einfachsten zu unterscheiden sind.

„Diagnostic characters:A blunt-headed fish with a stout body, and with heavy jaws forming a beak of 2 teeth in both upper and lower jaws. Dorsal and anal fins set far back, near caudal fin, dorsal and anal fins with 10 or 11 soft rays (no spines); pectoral fin with 17 to 19 rays; pelvic fins absent. Prickles are present from the snout to posterior margin of the dorsal fin, and chin to near the anus ventrally, and present laterally on the
cheeks and to near level of dorsal fin. Lappets are absent. Colour: dorsally and laterally, basal pigmentation is a light grey or brown with 6 dark, prominent, uniform, transverse bars; the first extending between the orbits, the sixth across the caudal fin; the lighter areas between bars may sometimes have shading; ventral surface, including the underside of the caudal peduncle, unpigmented. Size: Common to 300 mm, largest known specimens are near 350 mm (...) A fresh-water congener, Colomesus asellus, is similar but is pigmented on the underside of the caudal peduncle.“ (Shipp 2002, S. 1993)
