This species likes to eat tubeworms.
This species sometimes nibbles at clams including Tridacna species.
This species is not neccessarily aggresive, but it has a greater tendency towards aggresion then other species of the same genus.
These fish normally eat for the most part, coral polyps, therefore problems can arise in captivity when trying to give it an alternative food.
It is therefore essential to be well prepared before acquiring them and have several suitable food types ready to present them with.
However well prepared, there will be a large percentage, that will die after a short time in captivity.
It may mean having to keep living corals, mussels and zooplankton as food, in order to keep these fish alive whilst they are getting accustomed to alternative types of food.
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.
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 is well known for their long dorsal fin, hence the name Bannerfish.
The most interesting species of this genus are H. acuminatus and H. diphreutes, as they are the easiest to keep.
H. diphreutes, especially, is a good choice for aquarists who wish to keep Butterflyfish in a coral aquarium, as they are often reef safe if well fed.
The Butterflyfish are known for their attractive patterns and colours. They are closely related to Angelfishs, but can always be distinguished, as they lack the spines on each side of the head of the Angelfish.
A smaller group of these fish will seek out primairily soft corals, like Zoanthus. A larger part of the species will target different types of LPS corals. Butterflyfish are also known to seek out anemones, tubeworms and bristleworms.
Therefore it is important to choose the correct species in relation to the corals wanted, if one desires to keep Butterflyfish in a coral-aquarium.
Bristleworms, tubeworms and other small invertebrates are also a part of the diet for many Butterflyfish.
It can be problematic, with many of these species, to get them eating in the beginning, but many of the species cannot resist live zooplankton or live mussels with crushed shells. Another option is to mimic their natural behaviour by stuffing their food into coral skeletons or stones.
They ignore most other fish and are generally peaceful, therefore multiple Butterflyfish will have no problem living together. One should however be cautious about keeping similar species together unless they are a couple.
As these fish can be difficult to acclimatize and get feeding, it is important to buy healthy fish, to avoid having to deal with more problems. Make sure to check that they do not have parasites or any visible infections.
There are some species that should not be kept in an a aquarium, as they are food specialists and will almost always refuse to eat replacement foods. It can be possible to breed some species, which will eat frozen foods. Otherwise the only way to keep food specialists is by feeding them their natural diet, which consists of live SPS or LPS corals for example.
