Adolf’s Corridor (Corydoras adolfoi) – content, breeding

Adolphus Corridor (Corydoras adolfoi) Burgess, 1982

Adolf’s Corridor is a very elegant catfish, described only in 1982 and therefore rarely found in home aquariums. Received its name in honor of the Brazilian exporter Adolfo Schwartz.

Habitat: lives in nature in the basin of the Rio Negro in Brazil, in its upper tributaries, along the banks of slow rivers with sandy bottoms.

Description: oblong body painted in light beige or golden color with a silvery shade.

Distinctive features of the color of Adolf catfish are two black stripes. One begins behind the dorsal fin and stretches along the back to the tail.

The second, resembling a semicircle, girds the upper part of the head, passing over the eyes. A large orange or yellow spot is located between this stripe and the dorsal fin.

The fins are transparent.

The females are fuller and have a convex belly full of caviar.

The size of the corridor Adolf 55 – 60 mm.

Arrangement and parameters of the aquarium:
Peaceful schooling fish, for a flock of 6-8 somikov suitable aquarium from 100 liters.

Even better, the fish will feel in a group of 10 individuals. Adolf’s Corridor stays at the bottom, likes to poke around in the ground, so you should use a soft substrate, such as sand or fine gravel, so that the fish won’t damage the antennae.

Their coloring wins on a dark background. A lot of shelter is needed, which can be found in heaps of snags and overgrown plants that land along the back and side walls of the aquarium, thus providing more space for swimming.

Small fishes like muffled light, which can be provided with a moderate number of floating plants and feel much safer.

Water parameters: 22-26 ° C, dH 5-12, pH 5.6-7.5.

The content at the maximum temperature limit reduces the lifespan of corridors. The filter is necessary, as the fish digging in the ground muddy water.

Replacing a quarter of the water needed weekly.

Adolphus Corridor (Corydoras adolfoi) peaceful fish and gets on well with the same calm and medium-sized species. Sharing content with other dark-colored fish, such as small South American Kharatsinovye such as a black phantom, black neon or small species of Asian Rasbor, favorably emphasizes the color of catfish.

Nutrition: Like most Corydoras, these fish are omnivores and will eat food that sinks to the bottom of the aquarium. You can diversify the diet with dry foods with a high content of herbal supplements, it is desirable to use special catfish feeds in the form of granules and tablets.

It should be borne in mind that the main food is still live and frozen food such as Motyl, Artemia and Tubber.

A diverse diet of feeding will ensure the fish an optimal state.

In nature, they can often be seen adjacent to the anaconda, eating its old skin.

Reproduction: In accordance with the established practice of breeding Corydoras – Producers are selected in the ratio of two males and one female. The volume of spawning for breeding Adolf catfish from 25 liters, with fine gravel or sand.

It is necessary to create a light current, possibly with the help of additional dispensers along the glasses (this is where caviar will most likely be postponed) and raise the temperature by 1-2 degrees. You can put a small internal filter, filtering through peat is desirable.

Water parameters in the spawning aquarium: 25-27 ° C, DGH below 6, pH 6.5-7.0.

Before spawning, the producers should eat live food, and when the female has a belly belly, it is possible to stimulate the spawning of daily water changes to 50-70% with a decrease in temperature. The readiness of catfish for spawning is manifested in increased activity.

The female spawns about 25-30 eggs, after which the producers immediately settle out, as they eat caviar.

Most razvodchiki add a few drops of methylene blue or alder cones at this point in order to prevent the development of fungus on the roe.

1 day as swam, still with yolk sacs

The fry are hatching on the 4th day and for the next 3 days they feed on yolk sacs. Then you can start feeding on nauplii artemia.

Growing fry of Adolphus catfish is a rather laborious process, since the young are prone to diseases and are characterized by a high mortality rate, especially in the first days of life.

Spawning at these catfish is not difficult, but as practice has shown it is much more difficult to ensure the survival of the fry.

Special attention to water quality, daily water changes up to 95%! It should be noted that a change of chemical and temperature indicators of only two degrees can destroy the larvae and fry.

On feeding, there is an advice to start feeding the nauplii of a newly hatched Artemia, not forgetting to wash it in fresh water, other feeds may not be accepted initially and simply die of starvation. As fry grow, add to the diet other types of feed.

Some razvodchiki argue that the fry Adolph Corridor is easier to raise when co-feeding with other types of corridors, that the fry of other species help them learn to eat the food they offer.

Lifespan Adolph Corridor (Corydoras adolfoi) under favorable conditions of detention for 5 years.
