Hongslo's Dwarf Cichlid

Adults of this fish reach a length of 5–6 cm. Body coloration can vary depending on the specific region of origin and the degree of genetic mixing; hybrid offspring from different varieties of the same species are often found in aquariums. Males are usually larger and have a bright yellow coloration. During spawning, the upper and lower edges of their caudal fin acquire red hues, and the dorsal fin is adorned with a blue edge. Young or subdominant males do not possess these fin coloration features. However, symmetrical black streaks and a dark diagonal stripe crossing the head are present on their bodies. Females are smaller, have a gray coloration with a brownish pattern throughout the body, and their fins and tail are translucent.

Its natural habitat is in South America, specifically in southwestern Venezuela, in the Apure River basin, which is a left tributary of the Orinoco. These fish prefer small streams and rivers flowing through tropical forests. Such places are usually characterized by a riverbed abundant with snags (trunks, branches, roots) and fallen leaves. Decomposing plant remains release tannins into the water, giving it a characteristic brownish tint.

This is a peaceful and calm fish, but during spawning, males can show aggression towards their kin. In small aquariums, it is recommended to keep a group of one male and several females. They get along well with other species of comparable size.

For a pair of these fish, an aquarium of 40 L is sufficient; if the number of individuals increases, the volume of the tank should also increase accordingly. Hongslo's Dwarf Cichlids have been bred in artificial environments for many generations, so they are not very demanding regarding decor, which can be chosen by the aquarist at their discretion. If breeding is planned, it is important to provide shelters. These can be ceramic pots turned on their side, PVC pipes with a diameter of 5–6 cm, or other hollow objects. Despite their unpretentiousness, these cichlids look much more harmonious in an aquarium that mimics their natural environment. If there is an opportunity and desire, it is recommended to use a sandy substrate, several snags, and live or artificial plants. Lighting should be subdued. Dried tree leaves can serve as an additional decoration, which not only give the aquarium a natural look but also release tannins upon decomposition, which is characteristic of natural bodies of water. More detailed information can be found in the article “Which tree leaves can be added to an aquarium.” For successful and long-term keeping, it is extremely important to maintain stable water parameters within acceptable hydrochemical values and avoid the accumulation of dangerous concentrations of nitrogen cycle products, such as nitrites, nitrates, and ammonia. Aquarium maintenance includes standard procedures, the number of which may vary depending on the equipment used. Typically, this involves weekly water changes of 10–15% of the volume with fresh water, quality control, regular removal of organic waste, and preventive equipment maintenance.

In nature, their diet consists mainly of small invertebrates, which they find among fallen leaves and snags at the bottom. In aquarium conditions, they readily accept dry sinking foods, such as flakes or granules, if they are rich in protein. To enrich their diet, frozen or live artemia, daphnia, and bloodworms can be used.

Under favorable conditions, breeding becomes quite simple. During the breeding season, the male begins to actively court the female. When the female is ready to spawn, she lays eggs in pre-prepared shelters. The male is capable of fertilizing the eggs of several females, but he does not participate further in caring for the offspring. After spawning, it is recommended to temporarily place him in a separate tank due to possible aggression. Unlike males, females stay near the clutch throughout the incubation period and for some time after, until the fry grow up.

The main cause of diseases often lies in the keeping conditions: if they go beyond acceptable limits, immunity decreases, making the fish vulnerable to various infections inevitably present in the environment. At the first suspicion of illness, it is important first of all to check the water parameters and ensure there are no dangerous concentrations of nitrogen cycle products. Often, restoring normal, suitable conditions promotes recovery. However, in some cases, medication may be required. Detailed information on symptoms and treatment methods is presented in the "Aquarium Fish Diseases" section.

When choosing Apistogrammas, it is important to pay attention to the fish's activity and appearance. Healthy individuals should show curiosity, have clean, tightly pressed fins without signs of erosion or white coating, and clear eyes without cloudiness. Avoid specimens with sunken bellies, which may indicate emaciation or the presence of internal parasites, as well as fish that constantly hide or appear apathetic in the community tank. It is advisable to inquire at the store how long the fish have been imported, as adaptation to new conditions can be stressful for this species.
