Bunocephalus bicolor or catfish driftwood maintenance and care
Bunocephalus or Som snag (Bunocephalus bicolor)- Aquarium fish family Wide-headed catfish (aspredinidae).
The Amazon River (South America) is the birthplace of Bunocephalus.
LIVING IN NATURE
Bunocephalus bicolor (Synonyms: Dysichthys coracoideus, Bunocephalus bicolor, Dysichthys bicolor, Bunocephalus haggini.) Was described by Cope in 1874. It is found throughout nature in South America, in Bolivia, Uruguay, Brazil and Peru.
It lives in streams, ponds and small lakes, which are united by one thing - a weak current. He loves places with a lot of garbage - driftwood, branches and fallen leaves, into which he burrows. A loner, though small flocks can form.
The genus of Bunocephalus currently has about 10 species. Also a very similar species of Dysichthys is assigned to this genus. Being very similar in appearance, they have one difference in bunocephalus much more rough skin with a large number of spikes.
We can say that the genus is still not well studied and classified.
COMPATIBILITY WITH OTHER FISH
Som snag is the embodiment of peaceful fish. They get along well in a common aquarium, although being a nocturnal resident, it is shown very rarely. Can live both alone and in a small flock. It does not even touch small fish, but it does not tolerate large and aggressive fish, because all its protection is a disguise, and it weakly helps in the aquarium.
Although males and females of Bunocephalus look the same, an adult female can be identified by a fuller and rounded belly.
Appearance and gender differences
The body length of the bunocephalus is 15 cm. The fish has a flattened torso, in the region of the dorsal fin it narrows and acquires a conical shape. The caudal stem is moderately extended. Eyes of dark color are located on the head. Mustache only three pairs, maxillary longest. They are located around the perimeter of a long, stretched mouth. The tail of the bunocephalus is not very pronounced. The pectoral fins have a curved shape, they are large in size and look like wings. The very first ray of the pectoral fin has a tip at the end; it is thickened itself. The color of the fish is original, discreet. Bunocephalus resembles a snag; on its body there are light brown and dark brown spots. This color performs protective properties.
Sexual signs are not expressed. The female is distinguished by a denser physique.
Conditions of detention
During the day, the catfish hides in an ambush, pretends to be a rag or digs into the ground. Bunocephalum is an excellent masker, sometimes even in the most prominent place in the aquarium you can lose this fish. Catfish are most active with the arrival of twilight. Leaves a settled place, and prowls along the bottom, looking for food. Catfish do not conflict with fish of their size. A large mouth allows the chuncephalus to eat small fish. When choosing neighbors for a catfish, remember this. If you want to watch the fish, you will have to additionally install artificial lighting, since catfish are nocturnal residents.
The temperature suitable for bunocephal is 22-24 degrees. Equip the aquarium with a device that will provide continuous aeration and filtration. Hardness - 15-20 degrees. Artificial flow of catfish will only be a joy. Acidity - 6-7. Pour fresh, settled water regularly up to 25% of the volume. Equip the aquarium with shelters from plants, stones, build caves, grottoes. In the absence of shelters, the catfish will hide in the ground, burying itself completely in it. Peat, gravel, fine sand is the most suitable soil for fish. Beware of sharp fractions, they can injure the fish.
Bunocephals prefer food (dry, frozen) that drown. The favorite delicacy of catfish is meat feed. Since the fish are active at night, they should be fed in the evening. Bunocephalus is prone to overeating, try not to overfeed him. Dose the feed, then avoid problems.
Som snag in food is not pretentious and omnivorous. Often they feed on carrion and are not too picky in what will fall to its bottom. They prefer live food - earthworms, tubule and bloodworm. But they will also eat frozen cereals, pills for catfish, and everything else they find. It is important to remember that they are secretive and nocturnal, and will not be fed during the day. It is best to throw food shortly before turning off the lights or at night. Prone to overeating.
Like most catfish spawning of bunceocephalus occurs at night. In order to stimulate reproduction, the following is necessary: fresh, oxygenated water, a small hormonal injection and a fairly strong course in which the fish soar, as it were, snuggling together. Caviar runocephalus bright green, small in size, very sticky. Distributed throughout the bottom of the aquarium. No device is needed to protect the eggs in the aquarium; the fish do not touch their eggs.
One female brings from 200 to 300 eggs. Caviar matures in 35-48 hours at a water temperature of 26 ° C, then larvae appear. Somewhere in two days, the appeared fry are hiding in any crevices. Color in fish appears on the 4th - 5th day. Fry eat runocephalus the smallest living organisms (rotifers, nauplii cyclops). All this time, special attention must be paid to water quality. For the aquarist, the first month of life of the fry is the most difficult. At the age of one year runocephalus reach puberty.
