One of the most popular rarities today is the hypancecrus zebra belonging to the family of Loricariid catfish. Externally, a hydrobiont is very similar to a royal and blackline panac, only its color is more variegated.
On a snow-blue background, velvet-black diagonal stripes are perfectly positioned. Unlike its larger and more aggressive relative, hypantsistrus zebra is considered very graceful fish and absolutely harmless.
The maximum body length of an individual held in captivity is about 10 centimeters.
The first specimens of hypancestrus zebra began to be imported to Europe in the 80s of the last century and were then called pecoltius-zebra. In process of studying of fish by the Dutch scientists, fishes received the monotypic status.
In nature, these somas prefer the crystal clear waters of the great Amazon River. This circumstance in aquarium practice is fundamental. The best conditions for fish should be as follows:
- The total water hardness is no more than 12 degrees;
- Carbonate hardness – not more than 30% of the total hardness;
- Active medium reaction 6.2 – 7.5 pH;
- Water temperature 26 – 28 degrees;
- Powerful filtration and aeration of aquarium water;
- Regular changes in the amount of 1/3 – 1/5 of the total.
In addition, you will have to constantly monitor the general condition of the water, namely, the presence of bacterial turbidity in it and drastic changes in the chemical composition. As a rule, such fluctuations lead to extremely negative consequences.
If you notice deterioration of behavior in fish (catfish become secretive and try to isolate themselves), squeezed fins, occasional scratching, refusal to eat, it means that in the aquarium there have been serious changes in the chemical composition of aquarium water.
In these circumstances, the aquarist needs to take action immediately. First you need to stabilize the situation: the water temperature must be increased to 30-32 degrees, the volume of the aquarium should be increased to 300 liters at least and three times the flow of water should be increased.
In addition, you need to carry out prevention with tripaflavin or methylene blue in the proportion of 1-10 mg per liter of water.
New individuals must necessarily be subjected to anthelmintic measures, adding to the feed niclosamide or levamisole in the proportion of 100 mg of the drug for every 50 g of feed twice a day. It is also necessary for the fish to arrange quarantine. In order to prevent the development of gastrointestinal diseases, fish should be fed natural food (plankton, green algae, etc.), as well as high-quality artificial food should be fed to fish.
If for a long time to feed the fish with bloodworms, there is a high probability of developing allergic reactions with constipation, hydropsy of the skin and death of the fish.
Hypanzistrus zebra aquarists have learned relatively recently, but to a greater extent this fact is lucky. To prepare producers for spawning, the aquarist should pay close attention to feeding the fish.
It was noticed that most of the problem fish reach the necessary condition by eating only high-energy feeds, for example: crustaceans, caviar and softened fish tissue, mollusks, worms and softened tissues of the heart of cattle and chicken yolk.
Spawning should have dimensions of 150 × 50×50 itself with powerful filtering. In the aquarium for spawning hypancecrosis of a zebra there should be all kinds of shelters in the form of snags, ceramic pipes and other irreplaceable things of an experienced aquarist.
To increase the chance to get offspring, you must select at least 10-12 adult fish from the age of one and a half years and a body length of 6 to 10 centimeters.
Males, unlike females, are more slender and larger. In addition, in males one can observe multi-row spikes and whiskers near the pectoral fins. The culmination of marriage courting comes in spring and autumn.
Spawning occurs on previously prepared areas of the soil near the filters or aerators. As a rule, the number of eggs in one laying varies from 100 to 150 pieces.
Unfortunately, it survives about 1/3 of the entire offspring, because the larvae hatch more readily along the edges of the clutch, since at the periphery there is a more balanced oxygen regime. Starguns, artemia, and pills for vegetarian fish serve as starting food for the fry of the hypancecreus of the zebra.
During the month, the fry can reach 2 centimeters in length with good and balanced feeding.
If in the aquarium provided round-the-clock biological filtering, the hypancerus zebra quickly gets used to various non-aggressive neighbors of the same size. They can even get along with small Malawian and Tanganyik cichlids.
In addition, it was noted that catfish get along quite well with discussions in Dutch aquariums. The maximum lifespan of soms under optimal conditions of detention is about 5-6 years.
