Angelfish grow to be quite large and will require an aquarium of 55 gallons or larger when full grown. Tall aquariums are best, to accommodate their body shape. Water flow should be gentle, and décor should include large broadleaf plants and driftwood that is arranged vertically to simulate downed branches and trees. A few floating plants can also be added to provide shaded areas and cover. Substrate should be fine to medium grade, smooth surfaced gravel, as angelfish like to forage along the bottom for food.
