Angelfish: Quiet Beauties of the Aquarium

One of the most popular freshwater aquarium fish, the angelfish is known for its unique triangular shape. Long dorsal and ventral fins, almost as long as the fish's body itself, make these graceful beauties quite distinctive. They come in a wide range of colors, with the most common being the silver body with black vertical markings.

Angels are popular with aquarium owners because of their personalities. These fish are quite curious and will spend hours exploring their tanks. They can be trained to eat out of the aquarium owner's hands, and will often follow fingers along the glass of the tank. For an egg-layer, they are fairly easy to breed in captivity as well, adding to their popularity with serious enthusiasts.


Because angelfish can grow quite large, as big as 5.9 inches top to bottom, they need a tall tank. A tank with a height of at least 19.69 inches is ideal. They need at least 20 gallons of water. Angelfish thrive with a pH level between 6.0 and 9.0 to thrive. They need slightly soft water and prefer to live in tanks with live plants. Avoid putting angelfish in a tank with a known fin-nipper, as the long flowing fins are too tempting.


Angelfish like to eat, so provide plenty of food for them. Flakes or pellets can be a base diet for these fish, but make sure to supplement them with live and freeze dried foods. Angelfish really enjoy bloodworms and brine shrimp.
