Goldeneye cichlid (Nannacara anomala ) – attractive in appearance and behavior, a small aquarium fish from the cichlid family.

Occurrence

They live in the northern regions of South America , from the Aruka River in western Guyana to the lower bank of the Maroni River in Suriname. Found in quiet, flooded grasslands, in coastal parts of water.

Characteristics and disposition

Males are up to 7.5 cm long, females are clearly smaller and grow up to about 4 cm. In males, the dorsal and anal fins are larger and sharper, the torso is decorated with a series of triangular brown spots.

With age, during the breeding period, females develop a dark checkered pattern. The color of the male is rather olive green or blue with a metallic sheen, the back is brown-green. Blue fins. Females are less colored and are dominated by gray-yellow colors. Akarki are very attractive, durable and quite cheap aquarium fish, recommended for beginner aquarists.

As in the Apistogramma species, females in care display interesting body movements that communicate with the fry. By keeping a few males in smaller aquariums, a weaker individual, in order to avoid aggression from the dominant male, may become similar in size and appearance to the female. As soon as a dominant male is caught, in just a few weeks the weaker male will grow into the dominant male.

Nutrition and feeding

In the natural environment, they eat mosquito larvae and pupae. Goldeneye cichlids more eagerly eat live food (mosquito larvae, tubercles), but they can also be fed, frozen and dry food.

It is worthwhile to diversify your diet with foods with the addition of spirulina or finely chopped cucumber.

Aquarium

A pair of striped acares can be kept at least. A 54-liter aquarium (preferably larger), densely planted with lots of hiding places and nooks and crannies. The bottom can be decorated with rocks or roots from marshes. They can tolerate alkaline and medium-hard water, but they will feel better in acidic and soft water from 5 to 8 ° dH.

Outside of the spawning season, they are peaceful, non-aggressive fish that can be successfully kept in a social aquarium with other small, gentle fish with similar environmental requirements. In an aquarium that is too small, the female will be especially aggressive when caring for her offspring . In a South American biotope aquarium, tetras and silverfish will be good company.

Breeding

Very easy to reproduce. They can be kept in a community aquarium until breeding is scheduled and can be fed more frequently with live food.

For the time of reproduction, it is best to transfer them to a separate, min. 60 cm tank. In the breeding aquarium there should be a lot of plants and wooden or rock decorations, between which the female will find a shelter from too insistent male. It breeds on flat surfaces, stones, roots, less often in rock caves. After multiplication, the roles turn and the male seeks shelter from the smaller but aggressive female in this period.

The breeder should closely observe the situation in the aquarium. An intimidated male usually loses color and hides in a corner. An adult female lays 150 – 200 roe grains and guards them with great commitment. Hatching takes place after 2-3 days. After another 5-7 days, the fry begin to swim on their own.

At this point, the female can be separated. However, it is not necessary and if we decide to leave the female with the young, we will witness interesting communication between her and the fry. The fry can be fed with micro nematodes and brine shrimp larvae. The young grow at different rates, some after 4 months may reach 4 cm in length and others as little as 2 cm. They eat grindale (whiteworm) or ground dry food fairly quickly.
