Angelfish are native to a large area of tropical South America, including much of the Amazon River system. In their natural habitat, they are found almost exclusively in quiet, slow moving water. In the wild they prefer dimly lit areas, under overhanging vegetation or among trees that have fallen into the river.
While angelfish are generally peaceful fish, they are cichlids and can be aggressive toward one another, especially when attempting to pair off and spawn. Also, they will not hesitate to eat smaller fish. This does not mean they are aggressive, as many aquarists believe; like most fish, they are opportunistic and will eat anything that fits into their mouth. Suitable tank mates include larger tetras and rasboras, gouramis, peaceful barbs, rainbowfish, corydoras and other medium-sized catfish. Angelfish can also be kept with discus in larger aquariums, if the temperature is maintained above 82° F.
Angelfish will feed at the surface or mid-water, however, in nature they often forage along the bottom looking for worms and small crustaceans. They are omnivores and will thrive on Aqueon Tropical Flakes, Color Flakes, Tropical Granules and Shrimp Pellets. Frozen and live foods can also be fed as treats or to help induce spawning. For best results, rotate their diet daily and feed only what they can consume in 2 to 3 minutes, once or twice a day.
