Corydoras habrosus
Corydoras habrosus naturally inhabits the Orinoco River basin in western Venezuela and eastern Colombia, South America. During the rainy season, the river bursts its banks flooding meadows, turning them into swamps for a period of time. These fish stay in shallow water, near the edge of aquatic plants and among snags. The fish are undemanding and can be kept even by novice aquarists. Due to their modest size, these fish are prime candidates for a nano aquarium.
The body of the Corydoras habrosus is coloured pale beige. The abdomen is light and the back is dark. Along the entire body is a broad band of black spots. The dorsal and pectoral fins are transparent and the tail plumage has vertical rows of stripes consisting of small black dots. Males are slender, females have a rounded abdomen and are slightly larger than males. Males reach a size of 2 cm and females 2.5 cm.
The Corydoras habrosus is a peaceful fish. It is very calm and does not cause trouble for anyone. Keep these fish desirable group of at least 6 individuals. For such a number of fish suitable aquarium volume of 50 liters. Perhaps keeping catfish Habrozus in a common aquarium with other peace-loving fish, preferably occupy the middle and upper layers of water. Guppies, danio, tetras, rasboras etc. can be chosen as neighbours.
It is advisable to have sandy or dark-coloured, fine ground gravel in the aquarium as bottom material. Snags, ceramic pots and large stones can be placed at the bottom of the aquarium. The perimeter of the aquarium should be densely planted with a variety of plants.
Water parameters: temperature 20 - 26° C, hardness dH 2-18°, pH 6,5-7,5. Need aeration, filtration and weekly replacement of 1/3 of the aquarium water with fresh.
Preferably medium light of about 10-12 hours per day.
Corydoras habrosus feed on small crustaceans, worms, earthworms and algae in the wild. In the aquarium, the fish are fed with daphnia, artemia nauplii, small chironomids and various flake food containing spirulina. Catfish eat mostly from the bottom, so it is desirable to use sinking food.
Reproduction
Corydoras Habrosus corydoras reach sexual maturity at the age of 1-1.5 years.
Fish are bred in a specially designed for the purpose of spawning aquarium of about 20 liters. The spawning aquarium fish run in the ratio of 1 female to 2 males. The water must be soft. Spawning stimulated by lowering the water temperature by 2-3° C relative to that in which the fish were kept, as well as a daily replacement of 1/10th of the water in the spawning tank of fresh.
During spawning, the female spawns up to 80 eggs. The eggs are quite large, up to 1.5 mm in diameter. Depending on the water temperature, the eggs incubate for 3-5 days. The hatching larvae feed on substances in their yolk sacs for the first 2-3 days of their lives and then begin to swim and feed.
The fry are fed with artemia nauplii at least 4 times per day.
Corydoras habrosus has a life span of about 3-4 years under aquarium conditions.
