Classification: Taxonomy, Relation With Other Groups Clarions are members of the marine angelfish family Pomacanthidae, presently divided into seven genera. The genus Holacanthus "grooved spine" includes eight described species, four each in the tropical Atlantic and Pacific. I have espied this fish in small numbers around Cabo San Lucas at the southernmost tip of Baja, around the Cortez corner up to Cabo Pulmo.

Small crustaceans Krill, mysis, artemia Larger crustaceans Shrimp, crabs Aggressive This species can be extremely aggressive towards other fish. Regular feeding, plenty of hiding places and a lot of space can alleviate aggressive behavior to some degree. Can nibble at clams This species sometimes nibbles at clams including Tridacna species. Well established aquarium with algae These fish should be kept in a well run aquarium where they can "graze" algae from rocks and stones.

If there are insufficient algae on the rocks, it is important to feed more frequently and supplement with algae rich food e. Requires a varied diet This species must be fed with an appropriately varied diet.

Requires plenty of space for swimming. This species revels in swimming and requires an aquarium with ample space. This can, for example, be plant based fish flakes, Nori seaweed or similar. Hiding places This species requires places to hide, especially when newly introduced into the aquarium.

Tips for keeping Angelfish It is possible to keep various different sizes of Angelfish in the same aquarium, but it means that one must choose species with care and that the conditions in the tank are optimum. Here are some suggestions to increase the chances of success: Choice of species It is important not to choose species that are too similar, the greater the variance, the larger the chance of success.

It is also advantageous to choose fish of different sizes. Two young Angelfish of the same same size and pattern for example are a bad idea. One should of course avoid the most aggressive species. Order of introduction It is a good idea to make a wishlist and choosing the order so, that the least aggressive are introduced first. When adding similar sized Ange fish it works best if they are introduced simultaneously. Space There should be enough space in the aquarium, but it is difficult to give specific advice.

Of course there are exceptions to the table below as to just how big a tank should be in order to stand a good chance of success. Space itself is not enough, there should also be sufficient hiding places so the fish do not have to fight over these.

Water quality must also be very high, so that the fish do not get stressed for that reason either. Especially Zoathus are swiftly eaten by the larger species. It is however possible to build up a mixed coral aquarium with Angelfish. If some of the following corals are choosen there is a good chance the Angelfish will leave them alone; Hammer corals, Bubble corals, Star polyps, Disc anemones and others. Most of the SPS corals can be kept with Angelfish. Description These fish turn orange in adulthood and lose their blue juvenile markings.

Genus description Holacanthus Angelfish of the Holacanthus family are generally large, attractive and very colourful. Holacanthus are some of the hardier Angelfish, but they are still vulnerable to parasitic attack and need quality varied food with a good supply of nori and Spirulina. One must avoid a too protein rich food as this stops them obtaining enough vitamin A They are not reef-safe, but some of this species can, with a little care, be kept in a coral aquarium.

Holacanthus are known for their aggressiveness, so one must have a large tank to keep these fish. Especially the smaller ones are very quarrelsome. Family description Pomacanthidae Angelfish Pomacanthidae are known as some of the most colourful and impressive fish on the reef. Many species are not reef safe, as they especially target the soft corals and LPS. But by choosing your corals carefully, or by getting specific species of Angelfish, they can be kept in coral aquariums.

The demands of the individual species can vary widely. Danish common names.
