The Threespot or Flagfin Angelfish, Apolemichthys trimaculatus, does not commonly do well in captivity, unless the aquarist is willing to spend time housing it properly and getting it to feed. Lots of mature live rock is a necessity with algae, tunicates and sponges growing on it. This will enable them to feed off these natural foods on the rock until they can be coaxed into eating prepared foods with sponge material. Do not keep with boisterous feediers or any aggressive fish since it will hide, not feed and starve to death. They are bullied by dwarf angelfish. Provide a tank that is at least 100 gallons and plenty of hiding places.
Video of adult Bluefaced Angelfish with close up video of face and backside. They are more peaceful than other Poms but will still go after smaller peaceful fish. They are not reef safe and will snack on more corals. They grow to 15" and need a minimum tank of 125 gallons, but 225 gallons is best before they are adults. They will live over 21 years in captivity and will eat most prepared foods.
The Indian Yellow-Tail Angelfish (Apolemichthys xanthurus) also known as the Cream Angelfish or Smoke Angelfish. A hardy peaceful addition to your marine aquarium! The angelfish in this video is housed in a peaceful tank and looks quite fat and happy! They grow to just under 6", and do adjust quite well to captive care and need a tank that is 75 gallons or more. They are one of the more hardy members of this genus and can be kept with other angelfish if it is one of the first added to the tank. They are suited to a fish only set up with algae on the live rock to graze on, but some have kept them in a reef tank with lots of corals with some success. Feed foods with sponge material and Spirulina added if there is not an ample supply of algae in the tank.
Video shows yellow Herald's Angelfish, Centropyge heraldi, in among several dwarf angelfish. You can see the aggression between them which is due to the aquarium being too small. The Herald's Angelfish is not as durable as other dwarf angels, but one acclimated can do quite well if kept in a tank with a large amount of algal growth. They will pick at polyps of soft corals, large-polyped stonies, zoanthids, and clam mantles, so they would be best kept in a fish only tank. A male female pair can be kept in a tank that is at least 75 gallons or more.
The King Angelfish, Holacanthus passer, has various color morphs from juvenile to adult. Adult King Angelfish will clean Hammerhead Sharks, so hey if you happen to have a tank the size of most houses, get one! Otherwise a tank that is at least 135 gallons minimum is need for proper growth for this 14" angelfish! It is odd, but large angelfish, if their growth is stunted by a small tank, will result in their death! Their organs will grown to proper size, but if the body does not make it to the correct length, these organs are in essence are crushed, leading to death in about a year or so.
