Bunocephalus coracoideus (Bunocephalus coracoideus ) – colored clog (Bunocephalus coracoideus) – a freshwater catfish from the Aspredinidae family, with an unusual art of camouflage.
The species is found in Bolivia, Peru and Brazil. It lives in forest streams, lakes and ponds with lots of decaying leaves, sunken branches and other similar matter.
Characteristics and disposition
Clogs are not very large, usually not more than 15 cm. They have a flattened, long, slender, scaleless body, covered with horizontal rows of large warts, with a large head.
Their shape resembles a guitar or a banjo, hence their common name – Banjo Catfish. Thanks to their construction, they can easily hide under various objects. Compared to the rest of the body, the eyes are very small and difficult to see. The pectoral fins and the long tail are clearly marked. They lack the fatty fin and dorsal vertebrae locking mechanism common to most catfish species.
Gender very difficult to distinguish. Adult females are slightly larger and rounder around the abdomen. Due to their small size, they can fall prey to many potential predators. To survive, nature has equipped them with a very advanced camouflage that makes them literally disappear in the environment. Each individual has a unique pattern of brown or gray spots, which, together with numerous warts, effectively masks against the background of nature.
They are very gentle fish that do not hunt smaller fish and live in harmony with other representatives of their species. They can live alone or in a larger group in an aquarium. They spend most of their time stationary at the bottom of the reservoir, often buried in the ground. They show little activity mainly at night. For this reason, it is not a species for all aquarists.
Nutrition and feeding
Omnivorous . Scavengers in the wild. They are not picky in the aquarium, but prefer food of animal origin, live or frozen, e.g. bloodworm, earthworms, tubifex. You can also give them dry foods, necessarily falling to the bottom.
It should also be borne in mind that they lead a nocturnal lifestyle and can be shy when the lights are on and may then refuse to eat. It is good practice to feed them just before turning off the lights.
Clogs are inactive fish and therefore require relatively little space. The height of the aquarium is not important, but the base should be at least 60 cm long. There should be a lot of dark and poorly lit places in the tank.
For decoration, you can use wood, roots, stones and dry leaves, e.g. oak. Fish are eager to bury themselves in the substrate, so it is good that it should be at least a few cm thick. They are hardy fish that can tolerate a wide range of water characteristics. In the aquarium they can be kept with small, quiet species, e.g.
in the aquarium of the South American biotope with tetras, cichlids or other catfish, e.g. kiryskami, some armors. Their protection is based primarily on camouflage, so avoid the company of aggressive or very active fish.
Breeding clogs in an aquarium is difficult, but possible . It is best to breed them in a larger group of 6 or more adults.
Spawning takes place at night and the eggs are laid directly on the ground. Since the adults eat the young, it is necessary to prepare a separate aquarium where the eggs can be transferred. Hatching takes place within 3 days. The larvae, after using the yolk sacs, are large enough to accept micro nematodes or artemia larvae.
