Aquarium volume

Cichlazoma severum is a large and territorial fish, which means that the minimum volume per pair should be at least 130 liters. In addition to the volume for this species is important for the shape of the allotted housing. So in a high vessel, his body will take the form closer to the disk. And a low and wide dwelling on the contrary will lead to elongation of the body in length.

Soil

There are no special requirements for the soil. But it is better to use granite crumbs, small pebbles. For some ideas may be useful artificial soil. It is better to use its medium and large fraction. At the bottom must necessarily be large stones that form artificial boundaries. It is better to install them standing, imitating rocks. It is also necessary to install several stones so that their plane was inclined at an angle to the horizon. It is possible to use prepared driftwood, imitating driftwood in natural habitats.

Plants and Cichlazoma severum.

As all cichlids to plants is not indifferent, but if you pick up large plants with stiff leaves, they are likely to remain intact. In nature, cichlasoma northernum likes to hunt for small crustaceans in the thickets of plants. It can also eat the plants themselves. If you can not create a thicket of live plants, then you will have to create their imitation of plastic moulages. You can try to use valisneria spiral, fast-growing elodea Canadian, large species of cryptocoryne, peristolistnik, cattail. Thickets, whether live or artificial, will help to hide from the aggression of larger specimens of small fish when dividing the territory after the formation of pairs. Not found their place in the sun in this aquarium fish almost painlessly sit in the thickets or caves waiting until you find an opportunity to put them away in another aquarium or look for them a new owner.

Cichlazoma severum Water parameters

Ambient temperature for maintenance from 22 to 24 degrees Celsius. The hardness is 10 to 20 °dH. pH – 6,5 – 7,5. Fish like old water, but you should still change about 30% of the water volume at least once a month.

Lighting

This is determined not so much by the needs of the fish as by the needs of other aquarium inhabitants, in particular plants. The total power of fluorescent daylight lamps with a total power of 0.3 to 0.5 W/l should be used.

Aeration and filtration are essential for a dwelling with these fish. This is due to the increased metabolism of this species.

It is also necessary to regularly, at least once a week siphon the bottom, removing waste products of your pets.

Cichlazoma severum Compatibility

After puberty, when pairs are formed and the redistribution of territory begins, cichlasoma northernum can show quite strong aggression to members of their own species. Aggression also increases during spawning. It is associated with the need to protect their offspring. But again, the fish are more intolerant to representatives of their own species. With fish of other species can get along relatively easily, provided there is sufficient volume of the vessel. It is not recommended only to contain them with vuale or clumsy fish. All variettes of goldfish, small guppies, neons are not suitable for the role of neighbors for cichlasoma northernum.

Nutrition

It is indiscriminate in food. From live food can be given moths, trumpet fish, crustaceans of medium size, small or cut earthworms. It is necessary to feed with vegetable food – scalded with boiling water, shredded leaves of lettuce, cabbage, dandelion.

Cichlazoma severum breeding

Spawn can also spawn in a common aquarium. A separate spawning ground requires a tank of 150 liters. Spawning is stimulated in the same way as other cichlids – increasing the temperature of the environment by 2 – 4 degrees and the addition of fresh water. Caviar prefer to throw on an inclined or vertical plane. The female can throw out from 300 to 1000 eggs. Sometimes near the nest one can observe a mating dance resembling a waltz. It is performed by the couple with their mouths together.

After spawning, both spouses take care of the eggs by picking out dead eggs from the clutch and ventilating the live eggs with strokes of the pectoral fins. Incubation lasts up to seven days. Approximately as long as the larval stage. After the fry swim, they begin to actively feed. Their parents are able to feed them with a special secretion secreted by the epithelium of their skin. This can solve the problem of starter food. But it should be taken into account that the aquarium population over many generations gradually loses the parental instinct.

Cichlazoma severum feeding fry

This happens because of the nursing of the fry from generation to generation with the help of an incubator.

Centimeter length reach only to the thirtieth day of life. About the same time they become clearly defined camouflage coloration – several transverse stripes of dark shade, which disappear as the fish mature.
