Hello dear readers! Aquarium fish chromis in nature are widely found in various waters of the “Black Continent”.
In nature, chromis can grow up to 27 centimeters, but in an aquarium the space is limited and they are not so huge – no more than 12 centimeters. In aquarium conditions, fish with a length of 7 centimeters are ready to breed.
Chromis has a more elongated body than other cichlids, low dorsal and ventral fins, but they are strongly elongated. The dorsal fin in males has a pointed shape.
The coloring of chromis during spawning looks spectacular. The main background of the color during spawning is bright red, and blue-green dots are scattered throughout the body, fins and head.
A jar of chromis is desirable to be equipped with all kinds of shelters in the form of grottoes, caves and snags. A dense landing of large aquarium plants is welcome, because these fish are quite territorial. It is not recommended to place these shelters where you feed the fish.
Thus, you will not allow the penetration of fish into foreign territory.
Plants pick only large, which have a powerful root system and coarse leaves. If you do not want your pets to start digging in the places where the grass is planted, cover these places with large stones. On the pinch, you can take plastic plants, but as you know, in maintaining the biological equilibrium, such plants do not participate.
They feed chromis with live food, because under natural conditions they are considered predators and can catch small fish, for example, they can have guppies or neon in the aquarium. To diversify their diet, you can feed dry and vegetable feed, and sometimes give planed meat.
They contain and breed chromis under approximately the same conditions as are needed for other cichlids. It so happened that chromis is not compatible with other hydrobionts, and adult fish do not get along with the most popular inhabitants of the aquarium for one simple reason – excessive aggressiveness. Some problems may occur after spawning fish.
Growing young animals indulge in cannibalism, and leads to the fact that in one litter without sorting a couple of large and strong fish will survive. However, aquarists are not afraid of such difficulties in the content of chromis.
Venezuela and Colombia are considered to be the birthplace of butterfly chromis, where they grow to only 7 centimeters. These fish mostly live in the shallow waters of clean creeks and streams that belong to the Orinoco river basin.
Small butterfly hromis lack fussiness and relatively peace-loving nature makes it possible to keep them in a small aquarium. For a pair of fish enough 30-liter aquarium, which will be the same docile inhabitants.
In this case, it is better to choose an aquarium with a large bottom area than a height. But do not forget this: butterflies are cichlid, and cichlids are genetically territorial, which is especially striking when spawning.
On this basis, the compatibility of this representative of Tsikhlovy with other hydrobionts can be considered average. You can decorate the aquarium with chromis with a butterfly with elements that will emphasize the amazing color of these fish.
For these purposes, you can take a dark aquarium soil and not a bright background, use different shades of green, large stones of gabbro, basalt or granite. An excellent design option is considered a combination of several branched snags.
Illumination of the aquarium should be bright and it is desirable to arrange the lamp on closer to the cover glass. In aquarium conditions and with optimal conditions for the maintenance of chromis live more than 4 years.
Do not forget to pamper your pets with different types of food: cyclops, artemia, daphnia, bloodworms and pipemaker. Also, butterflies are not averse to eat granulated and flaky feed, but this is still not their main feed.
It is very useful to feed fish with foods rich in vitamins.
Parameters of aquarium water with chromis should be such:
- water temperature: 26-30 degrees,
- active reaction environment: 6, 0-7, 5 pH,
- water hardness (dH): 6-14.
This type of chromis is sensitive enough to change the quality and temperature of water. If you keep this fish in an aquarium with a high concentration of nitrogen compounds and low temperature, there is a high risk of causing various sores, such as tuberculosis and hexamytosis.
Change water regularly, once a week will be enough, but not more than 20%. If the water is quite sour and hard, then you need to take appropriate measures to reduce these parameters.
For these purposes, you can use distillate.
This aquarium fish is not strongly pronounced sex differences. Males are slightly larger than females, head is more massive, dorsal fin is more pointed. The female has a crimson or pink belly, but some variations are devoid of such signs.
If water is suitable for fish, then breeding them is not particularly difficult. Caviar female throws on a flat stone, like blue akara and turquoise.
During one spawning, the female can sweep away up to 200 eggs, which the male carefully carries into the ditch in the substrate.
Both the female and the male take care of the future offspring, but the further care of the roe is still on the male. In this case, the female is better to remove from the spawn. As noted, chromis butterfly is not a good parent.
Very often, parents ate caviar before the larvae hatch from it. In order to spawn was productive, it is better to spawn caviar in a separate aquarium, pouring water from the spawn in it. Active fry are fed with infusoria, and a little later with nauplii of artemia.
To make the fry grow better, take care of the quality of aquarium water. Aquarists have noticed that when crossing closely related individuals, the appearance of the fish deteriorates, so it is very important to provide a regular “tide” of fresh blood.
