Among aquarium cichlids, there are both calm and real fighters. The Nicaraguan cichlid belongs to the latter, but at the same time has such a bright appearance that many aquarists are willing to put up with its harsh temper. This pet will definitely not go unnoticed.
This fish is native to the freshwater bodies of Central America. Unlike many of its grayish counterparts, it is incredibly brightly colored. It has a golden-yellow body, often with a blue or turquoise sheen on its sides. But the most striking feature is its bright orange or even scarlet belly, which is why it is sometimes called the “red-throated” cichlid.
This fish is best suited to experienced hobbyists who understand its character. It is territorial, especially during the spawning season, and can be aggressive towards its neighbors. But for a species aquarium or the right company, it will be a real decoration. Its interesting behavior, care for its offspring, and regal appearance more than make up for all the hassle.
Description
The distinctive external characteristics of this cichlid are:
- stocky body, reaching a length of 25 cm;
- curved head;
- mouth located at the bottom of the head;
- golden-copper body color and greenish-blue head color;
- multiple dark spots on the fins;
- red edging on the tail fin.
When wondering how long these fish live, it is worth looking at their description. The average lifespan is 10-15 years.
Habitat in nature
The Nicaraguan cichlid was first mentioned by Günther in 1864. Its main habitat in nature is Lake Nicaragua in Central America. There are frequent cases when the described individuals were found in the Matina River in Costa Rica, as well as in the San Juan drainage.
Keeping and care
In order for the maintenance and care of the fish not to require special attention, it is important to observe certain water parameters when setting up their habitat:
- temperature – from 25°C to 28°C;
- hardness (dH) – from 8° to 15°;
- acidity (pH) – from 6.5° to 7.5°.
Lighting in the tank should be moderate. Fish need clean air, so aeration and filtration systems must be installed. It is a well-known fact that fish feel more comfortable in conditions close to their natural habitat. For this reason, it is better to choose soft sandy soil or substrate. Plants should be planted in small pots beforehand and only then placed in the aquarium. Otherwise, the fish will “dig” them up by the roots.
A quarter of the water in the tank should be changed weekly. In addition, it would be useful to purchase a siphon to clean the substrate of fish excrement and food debris. As for the capacity of the tank, there should be at least 100 liters of water per pair of fish. By creating the conditions described above, you can achieve the maximum lifespan for fish in a home environment.
Behavioral characteristics
The few breeders note that the cichlids described are pair-bonded creatures. That is, at the beginning of their life, they form a pair with which they remain throughout their lives. In principle, individuals are peaceful in behavior, but they may fight with other aquarium inhabitants for territory.
To create optimal conditions for the cohabitation of these representatives of the Cichlidae family, it is important not to overpopulate the tank, to release the fish at the same time, and to ensure that they are of the same age. It is important to ensure that the fish have enough hiding places where they can hide from other inhabitants of the aquarium.
Compatibility with other fish
This species is most compatible with:
- black-striped cichlazoma;
- elliot's cichlazoma;
- meek's cichlid;
- botia;
- nannacara.
It is not recommended to keep them together with cichlids of the following species:
- neons;
- rasboras;
- danio;
- astronotus;
- goldfish;
- gouramis;
- lalius.
Feeding
In natural conditions, as well as at home, this cichlid is omnivorous. It can be fed dry food as well as live food. The best options in the latter case are bloodworms, brine shrimp, tubifex, and coretra.
It is important to remember that the fish's diet should be as balanced as possible. Therefore, it is important to remember to use supplements. In this case, the best options are spirulina tablets, cucumbers, zucchini, spinach leaves, and lettuce.
It is important not to overfeed the fish. This means that one feeding per day is enough for them to get maximum energy. It is worth removing any uneaten food, as it will decompose and pollute their habitat.
The Nicaraguan cichlid is a bright and active fish from Central America that is often kept in home aquariums. It is calm towards other species but can be territorial with its own kind, especially during the breeding season. This cichlid is easy to care for and thrives in a spacious aquarium with rock and plant shelters. With proper nutrition and care, it lives a long life and delights with its rich coloration, especially in males, with iridescent blue-green spots on their bodies.
Sexual differences
Inexperienced aquarists are interested in how to determine the sex of the specimens they purchase. When they are young, this is practically impossible, so breeders recommend putting 6-8 fish in the tank, from which pairs will form in the future.
Adult individuals have pronounced sexual differences. Distinctive features of males are:
- large, fleshy body equipped with a pointed dorsal fin;
- the presence of black spots on the fins;
- massive bump on the forehead;
- not too bright body color;
- presence of a cone-shaped sperm duct near the anal fin during spawning.
Distinctive features of females are considered to be:
- bright coloration;
- well-proportioned body;
- rounded dorsal fin;
- presence of a trapezoidal ovipositor.
Reproduction and breeding
Given that males and females choose each other once and for life, it is better if spawning takes place in a separate, specially equipped aquarium. Its capacity should be at least 60 liters. Fine gravel is suitable as a substrate, where the female will dig a hole for laying eggs.
After the male fertilizes the eggs, the female cares for them, carefully sorting through them. The incubation period is known to be two to four days. First, larvae with a yolk sac appear. Five days later, fry appear, which must be fed with starter food.
The “parents” are kept with their young until the fry reach a diameter of 1 cm. Then the sexually mature individuals are moved to a common aquarium. If this is not done in time, the cichlids may eat their own offspring. The fish will be ready for breeding and reproduction at the age of 8-9 months.
The Nicaraguan cichlid is a truly bright and distinctive aquarium inhabitant. Its incredible coloration and active behavior will never let you get bored while observing the underwater world.
Keeping this fish is not that difficult, but it is important to remember its temperament. It needs space, clean water, and reliable neighbors of similar size. If you are ready to provide it with a suitable home, it will become a real long-liver and the center of attention in your aquarium.
In return, you will get not just a pet, but an interesting personality with habits that are endlessly fascinating to observe. From building a nest to caring for fry, it is a fascinating piece of living nature right in your home.
