Aphyosemion scheeli

Adult Aphyosemion scheeli reach 5–6 cm in length. A distinguishing feature of males is their larger size and vibrant coloration: a blue body dotted with noticeable pink specks. The fins and tail also have a variegated pattern with contrasting yellow edges. Females, as a rule, are smaller and significantly more modestly colored. Outwardly, this species resembles the closely related Aphyosemion gardneri, but differs in having fewer pink spots.

The natural habitats of this African fish are limited to the border regions of southeastern Nigeria and northwestern Cameroon. Here, it is found in small streams, rivulets, and lakes located deep within tropical forests.

Although these fish are generally considered calm and peaceful, males can show some animosity towards each other. In a small aquarium, it is recommended to keep a group consisting of one male and several females. When choosing tank mates, preference should be given to miniature and peaceful species, such as tetras, rasboras, or Corydoras catfish.

For a group of 4–5 Aphyosemion scheeli, an aquarium of 30–40 L will be required. A dark, soft substrate is preferred for decoration, as well as dense thickets of shade-loving plants, mosses, and ferns. It is also useful to place several snags or other decorative elements that can serve as shelters. Lighting should be subdued, and floating plants will help create additional shade and prevent fish from jumping out of the water. An important aspect of keeping them is providing soft, slightly acidic water. Filtration should not be excessively powerful to avoid strong water movement. In small aquariums, external or simple airlift filters can be used. Standard aquarium care includes weekly partial water changes with fresh water, regular removal of organic debris (uneaten food, excrement), and prophylactic inspection of equipment.

For these fish, protein-rich foods should be the main dietary component. These include live or frozen insect larvae, bloodworms, brine shrimp, and other small invertebrates. Over time, they may also get used to dry foods, such as flakes or granules.

Breeding this species does not present significant difficulties. The fish need to be provided with a complete diet and suitable spawning sites, such as dense thickets of fine-leaved plants or mosses. The incubation period for the eggs is about 14 days. It is advisable to transfer the hatched fry to a separate aquarium with similar water parameters. In the first days of life, they will need micro-food, such as infusoria or specialized suspensions. Later, they will be able to feed on brine shrimp nauplii and other similar products. Fry grow quite quickly, reaching sexual maturity by 4–5 months.

Creating suitable living conditions minimizes the risk of disease. The use of live food can pose a certain threat, as it is often a carrier of parasites. However, the strong immune system of a healthy fish successfully copes with such challenges. More detailed information on symptoms and treatment methods can be found in the "Diseases of Aquarium Fish" section.

When selecting individuals, attention should be paid to their activity and skin condition. Healthy fish should show curiosity, have no visible damage, sores, film, or signs of emaciation. Avoid purchasing fish that appear lethargic, constantly stay near the surface, or have clamped fins.

Since the species can be sensitive to transportation and keeping conditions, it is recommended to ask the seller about the current diet and water parameters. Avoid purchasing individuals from aquariums with clear signs of illness in their tank mates, as any stressful factors in the store can provoke hidden infections.
