Emerald catfish BROHIS or GREEN
Emerald brohis was introduced to Europe in the nineteenth century from Peru. In nature, these fish are found in waters of Ecuador, Peru and the Amazon headwaters. It is the oldest member of this species of fish living in home aquariums. These fish have become very popular among aquarists because of their activity, they exhibit in the aquarium, and the adaptability under any conditions. Fish have a size of up to 8.5 cm long.
Emerald brohis has a large head with relatively high trunk that gradually decreases to the tail unit. The flat sides of the fish are covered with two rows of hard plates that perform a protective function against the encroachments of predatory fish. Bladed tail unit. Boca fish have a greenish brilliant color, a bright yellow belly and back is pale brown with a slight tinge of green. Unlike the male has a tapered female dorsal fin, except that it is smaller in size and its abdomen less rounded than in females.
As with all types of catfish brohisy are nocturnal. They are very mobile and swim in small groups, so it is desirable to keep their flock of several fish, with a greater proportion of males. Fish swim in a substantially lower water layer, occasionally rising to the surface in order to swallow a bit of air. Brohisov can be kept in community tank with the same peace-loving fish, as they are.
To keep the aquarium for a spacious capacity of 100 liters, densely planted with plants, including floating. There must be a large number of shelters in the form of snags, rocks and caves. As the soil is desirable to use sand or gravel wiped. In the aquarium should not be any sharp objects, as Fish digging can damage his mouth.
The water must meet the following conditions: temperature 22-27 ° C, hardness dH 5,5-8,0, acidity pH 6,0-8,0. We need a good water filtration and its weekly replacement of 1/5 of the total volume of the aquarium. It should be noted that brohisy have additional gastrointestinal respiratory system and surfacing of water, they can breathe atmospheric air, so special requirements to aerate the water in the tank is not.
They feed on fish alive and frozen food (bloodworm, Tubifex, koretra), a variety of vegetable foods, etc. They feed on catfish taking food from the bottom.
Puberty in emerald brohisov comes to the age of one year.
To achieve spawning in aquarium conditions is quite a difficult task. Usually it is seeking through the introduction of injection. However, we know of cases where spawning took place in a natural way without the use of hormones.
Spawning Group. As spawning aquarium tank requires a volume of about 40 liters per pair of fish. To spawn need to plant manufacturers in the ratio of 1 female – 2 males.
The water temperature in the tank was raised to 27 ° C. The female buttonhole of about 300 pieces. sticky eggs on the leaves of floating plants or a large sheet of rooted plants. Immediately after spawning is necessary to transplant manufacturers.
The eggs are incubated for a week, after which the larvae appear that in a few days turn to fry. Since then, the fry begin to swim and feed actively. They are fed live with dust, rotifers, Artemia and dry food for fry. With good care of the fry grow relatively quickly.
Life expectancy in aquarium conditions, up to 7 years.
