Corridoras golden description, breeding, content, photo.
Among the wide variety of ornamental fish, there are many species whose representatives are not distinguished by a high level of fish intelligence, but are cute, funny, unpretentious. They are easy to maintain, they do not cause any special trouble. All these definitions can be fully attributed to a calm and peace-loving aquarium fish called "golden catfish".
A small, active and peaceful, bronze catfish (Corydoras aeneus) is a color variation of another species - the green corridor. Corridors differ in different colors - green, bronze, albinos, and even black, and like many other fish, a bronze catfish can be dyed to enhance its color. If you doubt the naturalness of the color, it is better to refuse the purchase. It is also worth looking at the condition of the mustache and abdomen, if it is sunken, then the fish can be tightened.
Like all corridors, the golden one is covered with bone plates for protection. In addition, the dorsal fin and body are covered with small spikes, and when frightened, it bristles with them. This is a protection against predators in nature. However, this interferes when you catch them with a net and you should be careful not to injure the fish. In the home aquarium, golden catfish is loved for its peaceful disposition, activity, and undemanding. And also a small size, up to 7 cm, and then they are females, and males are smaller.
Conditions of detention
Golden catfish easily adapts to the conditions of a home aquarium. Prefers water with a neutral pH level, soft, with a temperature of no higher than 18-26aboutC. A powerful filter should be prepared for the aquarium; the main soil is small pebbles, sand, and gravel. He likes to “flounder” in algae planted in pots. It prefers settled water, which is best diluted with fresh (once a week). You should abandon the aquarium with salted water - catfish can not tolerate it.
Schooling fish, 5 animals per flight are comfortable. A large number of shelters in the form of snags, stones, coconut and floating plants will create a sense of peace and security. Small fish can become neighbors of catfish, but it is better to keep aggressive large predatory fish in a separate aquarium.
Golden catfishes eat everything that falls to the bottom of the aquarium, picking food from the sand with their antennae. Omnivorous fish - can eat both tablets and dry and live food. If you keep different types of fish in one aquarium, make sure that the catfish feed settles well to the bottom. Feeding time - at night or in the morning. They love earthworms very much.
They eat any food: live, frozen and lyophized, as well as dry plant-based food: flakes or granules, there are also special tablets for bottom fish. Of live food, they especially love the tubers, bloodworms and artemia.
Golden catfish are fish-cleaners, they find and eat the rest of the feed, settled to the bottom. With an active search for food, they begin to delve into the ground, stirring up bottom sediments.
Males are slightly smaller and have a sharper dorsal fin. Since it is desirable to keep corridors in a flock, this question is not acute. Before spawning, they must be kept on a high-protein diet, which consists of small live food. Feed should be several times a day.
Spawning is preceded by a lengthy courtship ritual consisting of fights interrupted by harvesting potential spawning grounds. After the courtship is completed, the couple closes in the T-position: the female pushes the male with his head to the side, and he presses its antennae to himself with breast spikes. When the eggs are fertilized, the pair is disconnected and the female lays eggs.
Golden catfish often use aquarium walls, a plastic filter box, sponges or plant leaves for laying eggs. After spawning is completed, the eggs must be transferred to the spawning grounds, fry appear in 2-10 days.
This fish needs fine dark gravel or coarse-grained sand so that it does not damage its antennae. Do not place them in very high aquariums, as they periodically need to swallow air. A large number of shelters is important for them, the aquarium should be planted with long-stemmed and bush plants, and it is also good to put a few smooth stones, a scab. Do not forget that in any aquarium you must leave free space for swimming.
You can distinguish a female from a male by size, females are always much larger and have a fuller and rounded abdomen. However, guaranteed differences between females appear only in adulthood. Usually, a lot of juveniles are bought for breeding, which eventually create pairs themselves.
