Corydoras Species

I think a lot of people have raised fish Corydoras it, then you are sure that you have Corydoras Corydoras is the true meaning of Corydoras Corydoras is a wide range of designations, not called Corydoras, it is Corydoras, the real Corydoras generally have scales, tentacles, pectoral fins on the sharp spines, the true Corydoras generally have scales, tentacles, pectoral fins on the sharp spines, the true Corydoras is the true Corydoras, the true Corydoras is the true Corydoras. The real Corydoras have scaly armor, antennae, and sharp spines on their pectoral fins. The real Corydoras belong to three genera in the subfamily Aspidoras (Anopheles), Brochis (Bowfin catfish), and Corydoras (Armored catfish), so you can’t go wrong by choosing one of the three genera if you want to keep a Corydoras.

For the sake of convenience, the following abbreviations are Aspidoras (A catfish) abbreviated as genus A, Brochis (bowhead catfish) abbreviated as genus B, and Corydoras (A catfish) abbreviated as genus C. The most common and most common of the Corydoras we keep are Aspidoras (A catfish), Brochis (Bowhead catfish), and Corydoras (A catfish). Corydoras is a large group of catfish with many different colors and new species often appear, which can be divided into the following groups according to the different positions of the eyes, differences in the shape of the skull, the shape of the pectoral fin spines, the ratio of the head length to the length of the carapace, and the differences in the markings:

1, spotted catfish group, representative species: white leopard rat, king leopard rat, three line leopard rat

2, whiskered catfish group, representative species: flower rat, orchid rat, space flying rat

3、Olive armor catfish group, representative species: coffee rat, panda rat, Indian rat

4、Leopard catfish group, representative species: moonlight mouse, blue moon mouse, elf mouse

5、Spike-snouted A-Catfish group, representative species: emperor rats, black arrow rats, long-waisted rats

Corydoras is a huge family, the species can be up to hundreds of species, the above is only listed a small part of them, the species of Corydoras is part of what we need to know, more importantly we need to know the habits and feeding of Corydoras.

Corydoras Breeding

Corydoras have a long history of existence, which is inseparable from its tenacious vitality, the development of the present, Corydoras habits have tended to stabilize, there is a certain rule to follow, in the breeding of Corydoras, we can according to his habits to create a comfortable environment for it. Generally speaking, we need to pay attention to the following aspects when keeping Corydoras.

1, water quality, pH value should be close to neutral.

2, water temperature, water temperature range of 22 ℃ -26 ℃ is good, the highest do not exceed 30 ℃.

3, filtration, filtration must be strong, it is best not to use water filtration and bottom filtration, it is recommended to use on the filter or external filtration.

Corydoras can be regarded as a good class of ornamental fish, in the breeding, do not have to change the water often, they like the old water, change the water too often but will make them suffer from skin disease, because Corydoras native place is in South America, they like fast rivers, in order to make it faster to adapt to the environment, you can increase the water flow appropriately, to get a water pump is still necessary. Corydoras also need some shelters or hiding places for them to rest, so you can put some sunken logs when keeping them.

Corydoras feeding should not be too dense, to leave it a certain amount of space for activities, you can fish according to their own situation, feed, red worms and earthworms are its favorite, but do not feed too much, be careful he will be indigestion, the main bait is still feeding, now on the market Corydoras special feed is still good, and Corydoras is not picky about what to eat, can be used! Corydoras are not picky eaters, you can adopt the feeding method of more quantity and less times, about 2 to 3 times a week will be fine. Finally, you should pay attention to regular water changes, which will help them grow faster.

Corydoras Breeding

Breeding of Corydoras is relatively simple, the water temperature will be lowered for a short period of time during the water change, which will stimulate Corydoras to come into heat and spawn, and the most common way for Corydoras to spawn is the “T-breeding”. When the female gives her consent, the male will stretch out his genitals from the lower part of his body, and the female will suck the semen out of her mouth and hold it in her mouth, and then the female will lay her eggs in the right place and eject the semen onto them. Generally, Corydoras will lay their eggs on the glass wall or water plants, or even on the bottom sand, which is very close to the surface of the water.

When the eggs are laid, the eggs need to be collected in time and put into another incubation box for incubation, after three days or so, the small egg fry can hatch out, this is the small fish’s ability to swim is very weak, pay attention to the fact that after two days, the small fry comes with the nutrients in the yolk sac will be gradually absorbed, which is the ability to be active is very strong, the next thing to think about is the feeding of it, you can give feeding some Frozen shrimp, frozen bloodworms, fresh earthworms and JBL’s old Corydoras patches are all fine.

Corydoras spawning need to change the surrounding environment, spawning Corydoras is more sensitive, can be planted in the tank some easy to manage water plants or submerged wood, try to minimize the sense of pressure to it, at the same time to give him a shelter, resting place, which is the current does not have to be too fast, keep it medium good.
