This species grows very quickly if fed well.
This species sometimes nibbles at clams including Tridacna species.
This species demands a high water quality.
Amongst other things it means, that water must be properly oxygenated.
This species needs a very large aquarium when fully grown.
Exactly how big the aquarium should be is hard to say, but the size of this species is such, that it cannot normally be kept in a home aquarium.
This species can be extremely aggressive towards other fish.
Be careful when keeping these fish together with peaceful or docile species. Regular feeding, plenty of hiding places and a lot of space can alleviate aggressive behavior to some degree.
This species must be fed with an appropriately varied diet.
This species will better acclimatize to the aquarium`s condition if introduced, when young.
Very small individuals can be very delicate.
This fish requires feeding several times a day, especially when newly added.
When the fish can find its natural food in the aquarium it requires less frequent feeding.
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.g. Spirulina.
They can live as a pair provided they are introduced simultaneously.
This species needs good hiding places, for example, between live rocks.
This species revels in swimming and requires an aquarium with ample space.
This species can make a grunting sound when it feels threatened for example.
This species can change gender from female to male.
When a male is needed, a female changes sex and takes on the role.
This species can be very shy when first introduced into a new aquarium.
More aggressive fish can be introduced after this species has acclimatized.
This species can refuse to eat when newly introduced.
Normally however, they begin to eat within about a week, but it's advantageous if they can find their own food in the aquarium.
It can be a challenge to keep corals together with Angelfish, since the latter eat most soft corals and LPS. 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.
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.
100 gal (400 liters): Several small Angelfish (<15cm) can live together.
240 gal (900 liters): Several medium Angelfish (< 20cm) can live together.
400 gal (1500 liters): Several large Angelfish (<25cm) can live together.
Food and water quality
It is always helpful to give the fish a varied diet, so they can withstand the occasional stress situation when for example new fish are introduced. Water quality must also be very high, so that the fish do not get stressed for that reason either.
The Pomacanthus genus of Angelfish, is extremely impressive with their beauty of colours and patterns. They live mostly on most sponges, but also soft corals, tunicates and macroalgae found naturally.
There is typically rather a large difference in the appearance between juvenile and adult.
When properly fed, these fish can grow fast and become very large. In captivity, it can take well over a week for these fish to start feeding. This, because they are not used to catching their own food in the aquarium. It is best to feed them little and often, 4/5 times daily.
As the feeding indications suggest, these fish are not reef safe, but if one chooses the corals with care, it is possible to keep them together in a aquarium.
One may obtain a species specific preparation containing sponges to meet nutritional needs of some species. Thier diet should include algae based foods, i.e. nori seaweed, spirulina, or similar.
Pomacanthus species can be very aggressive, but not to the same degree as the Holacanthus. Thus in a tank with shyer species it is best to add a Pomacanthus last.
They must also not be kept together with Lionfish, Seahorses, Scorpionfish or similar, as they might be nibbled.
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.
There are Angelfish suitable for most aquarium sizes, from Dwarf Angelfish which are well suited to smaller aquaria, to the larger of the species which can be impressively displayed in a larger aquarium.
The demands of the individual species can vary widely. Some are food specialists and require therefore special food, while for others can be difficult to acclimatize, as they live in deep water in the wild. It is recommended that one has a reasonably good knowledge of the different types of food and of treatments of illnesses, if one wishes to keep the larger species.
