Refers to the single barbel.
Monocirrhus polyacanthus are very sensitive to poor water quality. Because they produce a lot of ammonia due to their protein rich diet it is important that their aquarium is equipped with excellent filtration and that a good maintenance regime is adhered to.
Carnivore, most individuals will only accept live food. Juvenile fish will accept live aquatic inverts but older specimens may only accept live fish. In the UK it is illegal to use live vertebrates as food.
Predatory but peaceful with fish which are too big to swallow whole. Does best when kept in a species tank.
Very difficult, females appear more rounded when coming in to breeding condition.
Aquarium breeding has been accomplished, a rise in both temperature and pH will help to trigger spawning in a well conditioned and compatible pair. As many as 300 eggs could make up a single brood. The adhesive eggs are normally laid on the underside of a large leaf. After spawning the male assumes the dominant role in caring for the brood and the female should be removed from the breeding tank.
Monocirrhus polyacanthus has not been evaluated by the IUCN Redlist of endangered sspecies.
Acidic water inhibits the growth of pathogenic bacteria, in harder more alkaline conditions these bacteria flourish and Monocirrhus polyacanthus is not equipped to deal with this. Unless the fish is kept in very soft acidic conditions it is likely to fall victim to various opportunistic infections which will eventually lead to its early demise.
