For more details on the overall characteristics, compatibility, diet and feeding of this and other saltwater Angelfishes, refer to our .
The Keyhole Angelfish are found alone or in harems of 3-7 individuals. They inhabit mixed coral and rubble areas of lagoons and seaward reefs, feeding primarily on algae and some and crustaceans. The depths they are found as adults is from 13 to 180 feet (4 to 55 m).
These angelfish can be a challenge to keep due to their nutritional needs as adults, and are really only suited for advanced aquarists. Although juveniles are easier to feed, eating more algal type foods, adults are very dependent on sponge material for nutrition. Because they are a smaller size one would think a smaller tank would be fine, but the dietary needs of this angelfish dictate a larger tank. They are also timid fish that needs a calm environment and plenty of caves and crevices within rockwork for places to hide. They need a mature tank of at least 100 gallons that has live rock with lots of encrusting sponge material and plenty of algae growth to help them adjust and to maintain them. A varied diet that includes sponge material specifically designed for marine angelfish has been suggested as well to make sure they get their needed nutrients.

How often to feed angelfish juvies
It is well established that reproduction is sensitive to the state of energy reserves, and that there is a balance between energy homeostasis and fertility. In this view, this study examined the effects of different diets on growth and reproductive performance of fresh water angelfish. Twenty four pairs of angelfish (weighing 3.58 ± 0.24 g) were fed with four types of diets including live earth worm (LEW), dried Tubifex (DT), dried Gammarus (DG) and prepared granulated feed (PGF), twice a day for 90 days. Reproductive parameters were measured between days 60 and 90. The significant increase in the gonadosomatic index (GSI), fecundity and hatchability brought about by the LEW were demonstrated by the higher number of spawned eggs and hatched larvae. The best growth observed significantly in PGF, and length of larvae was enhanced in this group, consequently. The numbers of dead and deformed fry were lower in the fish fed with PGF and LEW, but there was no significant difference among experimental groups. This study showed that breeders benefit from inclusion of prepared granulated feed and living earth worm during their growth and reproductive stages, and simultaneous using of them for achieving better results is suggested. The purpose of this study was to examine the effect of various diets including living earth worm (LEW), dried Tubifex (DT), dried Gammarus (DG) and prepared granulated feed (PGF) on the growth and reproductive performance of fresh water angelfish (Pterophyllum scalare).Artificial diets, which are normally elaborated with dried live organisms processed in different presentations such as flakes, meals or small pellets, are also used. Although it is known that the angelfish accepts artificial diets, lower growth and survival rates of P. scalare are commonly obtained when such diets are used as the sole feed.,The freshwater Angelfish is a very popular tropical fish because of its unique shape and because of their interesting personalities. Freshwater angelfish are aggressive eaters and will go to the top of the tank when they see you approach. Because of their aggressive feeding habits, make sure that your less aggressive fish are getting their share around feeding time.
