The dragon (Corynopoma riisei) lives in the waters of Northern Venezuela and Lake Trinidad. In 1932, fish of this species were first brought to Europe.
They grow up to 7 cm in length. The scales very beautifully shimmer in different colors: silver with a touch of gold and green, sometimes you can also distinguish between violet and blue.
In mating games, the male attracts the female using outgrowths on the gill covers. At the end of these outgrowths there are dark lobes, which the male points to the female, thereby inviting her to mate.Dragon fish (Corynopoma riisei).
These fish reproduce quite differently than others. The male lays his milk, which are enclosed in spermatophores, near the female's genital opening.
Before the testicles finally mature in the oviducts, the female wears the same spermatophores in them. Due to this, she can throw caviar not once, but several times, even in the absence of a male.
It is interesting that she does this almost imperceptibly. Sailing past the plants, the fish, it would seem, gently touches them, and it was at this time that the eggs attached to the surface of the algae.Dragon fish is a small resident of aquariums.
However, the female should engage in throwing in another aquarium, with a volume of at least 20 liters. Therefore, immediately after fertilization, it must be transplanted, and small-leaved plants should be placed there. The water temperature should be kept at 24 ° C, dKH less than 2 °, and a pH of 6.5-7.0. After 20-36 hours and larvae hatch.Keeping dragons in aquariums is not too laborious.
After the fry begin to swim, they can already be fed artemia and cyclops larvae.
Dragons are usually kept in groups. There should be twice as many females as males.Dragon fish is not fastidious in food.
These fish are not whimsical to food, and are ready to eat any food. The water needs to be kept clean and a sufficient amount of algae should be provided in the aquarium.
