A) Alert - This fish cannot be kept with other Angelfish. If you're attempting to purchase two or more Angelfish for the same aquarium it will cause them to fight and most likely one will not survive, so if you're placing an order that has 2 or more Angelfish in it we will have to place the order on hold until we're able to contact you to ensure you're not putting them into the same tank. If you understand they cannot be kept together, but would like to purchase two or more in the same order(separate tanks, group order, etc.) you will need to write in the Special Instructions area at the end of the shopping cart that you understand they cannot be kept together. Tremendous time and effort is put into ensuring the health of these fish and it is very important that you're fully aware two Angelfish should not be kept in the same tank.Black body with a vertical white spot just behind the head, anal and pelvic fins are yellow. As the fish matures a thin blue line develops around the edge of the dorsal and tail fins. Keyhole Angels can grow up to seven to eight inches long (18.5 to 20 centimeters) at maturity.Algae and other vegetable materials are offered in conjunction with mysis shrimp, spirulina, or other protein items. Live, frozen, and prepared formulated foods are also available to use with Keyhole Angels.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.
