The Halfblack Angelfish is gray-brown from the tip of the snout to the beginning of the anal fin. The anal fin, much of the dorsal and the rear of the body and tail are black. There is also orange trim on the gill cover and the base of the pectoral fin.Most mature Half Black Angels measure up to four inches in length.It is important to provide Dwarf Half Black Angelfish with plenty of good quality cured live rock and a well aquascaped aquarium with caves, archways and overhangs to swim through or hide in.The Angelfish family is a group of colorful and elegant fish that are adored by boththe serious and casual observer. These fish are mainly available to the hobbyistunder the Genus Pomacanthus and Centropyge. Pomacanthus Angels are the larger morerobust species. The Centropyge Genus are made up of smaller fish that feed primarilyon algae from the reef surface. The adult Pomacanthus Angels usually have longdorsal and anal fins and a rounded face. The Pomacanthus Angels will change colorquite dramatically from their juvenile stage to adult stage. The Centropyge Angelsare found predominantly in the Indo-Pacific while only a couple of species, like thePygmy and Flameback Angels, are found in the Atlantic and Caribbean. At the sametime, the Pomacanthus Angels dominate the Atlantic and Caribbean while in theIndo-Pacific they are less prominent. The Centropyge Angels do not change colordramatically from their juvenile stage to adult stage. These smaller Angels areoften seen milling around reefs which they use for both shelter and as a foodsource. Angelfish are differentiated from Butterflyfish by the small spine thatextends from the bottom of their rear gill cover.
