Ageneiosus magoi
Ageneiosus magoi is a rare fish in aquarists' collections. In nature it lives in the Orinoco River and its tributaries in Colombia and Venezuela.
Ageneiosus magoi can be distinguished from other members of the genus by its basic yellowish coloration and characteristic intermittent stripes that usually reach to the root of the tail plumage. The body is elongated and slightly flattened on the sides. Males are decorated with a peculiar hump with a curved dorsal fin with a sharp spike at the end. Coloration varies greatly depending on where the fish live. In individuals caught in the wild, the body and fins are dotted with yellow spots, which completely disappear when the fish are kept in aquariums. These fish are also characterized by a mouth with a deep dolphin-shaped notch. The size of the fish reaches 18-25 cm.
Ageneiosus magoi are fairly hardy fish that adapt relatively quickly to life in the aquarium. Keep the fish can be as singly, and a small group, and should take into account that one individual needs at least 150 liters of water. Keep the fish in a common aquarium with other fish, but in this case be aware that, although Ageneyosus and peaceful to neighbors, they will prey on any fish that can fit in their big mouth.
The aquarium should have a large variety of hiding places in the form of grottoes, rocks and snags. It is desirable to plant tall plants around the perimeter of the aquarium. It is important to create shaded areas in which the fish will hide.
Water parameters: temperature 22-28° C, hardness dH 2-12°, pH 6,0-7,0. Requires filtration, increased aeration and a weekly substitution of 1/3 of the aquarium water with fresh. Create a flow of water, for example, by directing the diverter nozzle water filter along the back wall of the aquarium or using a water pump.
The menu of Ageneiosus magoi in the aquarium is mostly fishy. After the fish adapt to aquarium conditions, they can be accustomed to lean meat and beef heart. The fish are also given shrimp, mussels, earthworms. Food should be strictly dosed, because Agyneiosus do not know the measure of food and are prone to overfeeding.
Reproduction
Ageneiosus magoi can be bred under aquarium conditions. The reproductive process itself is poorly understood.
Fertilization is internal, through a special copulatory organ formed by the first rays of the anal fin. Males have a sexual organ - the gonopodium. With its help, he inserts milk into the female's body. During the mating season, the male swims next to the female and his tubular gonopodium is turned forward to introduce milk into her reproductive tract. After the female is fertilized, her pregnancy can continue for many months.
