Carpet eleotris: content and reproduction in the home aquarium

Carpet eleotris belongs to the Goloveshkov family. The color of the fish is very beautiful – all over the body there is a scattering of pink-red and blue stains that resemble an oriental carpet. Because of this coloring, the fish got a similar Russian-language name.

The male has a rounded head with a prominent forehead, a belly of a flat shape. The maximum size of a male is no more than 6 centimeters. In females, the head is elongated, and the belly is convex.

Females are slightly smaller than males – from 4 to 5 centimeters. A hydrobiont can rightly be considered a relative of rotan-shingles, which is found in almost all waters of the European part of Russia.

However, unlike its kinsman, carpet eleotris is a peaceful aquarium fish that gets along beautifully with small fish, such as swordtails, mollies, petilias, guppies, red neons, rhodostomoses, ornatus.

The hero of our today’s article from New Guinea comes into being, in reservoirs of which a lot of stones and skimmer are concentrated on the bottom. All of these things create a large number of shelters where the males of Eleotris hide themselves.

The females of their permanent refuge does not exist and they patrol between the burrows of the males. The waters of the rivers of New Guinea are constantly mixed with the tide of the sea, thereby increasing their salinity.

Hydrochemical parameters of water in natural habitats of eleotristes are as follows: weak alkaline reaction (7.2 – 7.5 pH) and hard water 12 – 15 gH.

In order to maintain a carpet eleotrix, it is necessary to adhere to the above water parameters and set the water temperature within 22 – 24 degrees. The modern generation of eleotristes is already so domesticated that salting does not matter.

As neighbors in the aquarium with a carpet eleotris, peaceful small-sized small fishes will suit, such as: leopard danios, iris or mollies of the wellifera.

The number of shelters in the aquarium should match the number of males. Otherwise, frequent clashes over the territory may occur.

As a rule, each male selects for himself a shelter into which he will squeeze with great difficulty. Larger holes or pots will be carefully ignored by fish.

If you are using an internal filter, check the size of the inlets. If they are large and the male can squeeze through them, he will definitely do it and eventually will die inside the filter.

For spawning a pair of carpet eleotristes, a spawning tank with a volume of 5 liters or more, in which the water level should not exceed 20 centimeters, is suitable. There it is also necessary to place a small flower pot on its side, or a plastic pipe sealed at one end with a diameter of up to 5 centimeters.

This refuge will become a spawning substrate for fish. At the bottom of the aquarium fit a bunch of Java moss, which must be secured with a small stone. The temperature of the water in the spawning should be 27 degrees, and the future parents are fed abundantly with live bloodworms and red daphnia.

The lighting in the aquarium should be around the clock.

After 24 hours, the male will begin to actively pursue the female, inviting her to his refuge. In males that are ready for breeding, the forehead becomes even more prominent, which leads to a curvature of the upper jaw.

In a female ready for spawning, the belly turns orange. The process of an active invitation to the shelter can last from days to two.

Ultimately, the female dives along with the male for shelter and the pair does not show for a long time. Spawning is carried out on the tube wall for several hours, at the end of which the male becomes aggressive towards the female and drives her out of the nest. All caviar will be delayed when the female has a flat belly.

At this point, the female is better to transplant back into the general aquarium.

The male left alone with the offspring practically does not swim out of his shelter. If the male is removed from the spawning vehicle, it is possible to reduce the release of larvae.

Caviar develops under the supervision of a male for 4 to 5 days. After hatching, the larvae will hang on the walls of the shelter for a few more days, and then they will begin to fall to the bottom of the aquarium. At this point, the spawn must be removed from the male.

In the monastery of fry it is necessary to include weak aeration, lower the water level by half and create a weak current. A day later, the fry will have to swim independently in the aquarium.

When the fry begin to swim independently, they can be started to be fed with ciliates or special fry feeds from the companies Tetra and Sulfur. Consider the fact that fry of carpet eleotrix are extremely inactive. They react to food only if it goes past their snouts.

The fry begin to eat more actively at 2 weeks of age. From this point on, the young begin to actively grow and double in size over the next week.

When this happens, the light in the aquarium at night can be turned off and periodically produce partial water changes in the spawn. When the young growth reaches 1 centimeter in length, the growth stops and by about 6 months the fry become already 4 centimeters in length.

From this point on, the first sexual differences between individuals appear, and after another three months the fish reach sexual maturity.
