Philippine Blue Angelfish make great centerpiece fish for larger sized aquariums of at least 20 gallons. This color morph gets an intense blue once they mature. They come in a variety of different types including: blue ghosts, blue smokies, blue zebra, paraiba, smokey paraiba, and blushing paraiba. Angelfish have long ventral fins that flow gracefully as they swim throughout the tank. Their long dorsal and anal fins give them a lot of height, so taller tanks are recommended for these fish. Once they get adjusted to the aquarium, you can see how eager they are to eat. They swim right up to the front whenever they think they are about to be fed. Angelfish can get aggressive once they are mature, so adding in decorations or plants to block their line of sight in the tank would help reduce aggression.
