Peckoltia

Adults of this species reach a length of 9–10 cm. The catfish is characterized by a large, robust physique, especially noticeable in females. Males, on the other hand, appear somewhat more graceful. The coloration consists of dark spots on a background that can be gray or yellowish; the exact shade depends on the specific population and its region of origin.

Its natural habitat is the waters of South America, specifically the Tocantins River basin, located in the Brazilian state of Pará. The catfish is found in a wide variety of biotopes, from overgrown swampy areas to fast-flowing river currents. These fish prefer to stay in the bottom layers, finding refuge among snags.

This is a peaceful and calm representative of catfish, especially if kept in the company of fish that inhabit the water column or its surface. Intraspecific competition (mainly among males) or rivalry with other bottom-dwelling species for territory on the bottom may arise if the tank volume is insufficient.

For one or two fish, the optimal aquarium volume starts from 100 liters. Keeping Peckoltia is considered quite simple, provided that a suitable environment is created for it. Favorable conditions are ensured by maintaining stable water parameters within acceptable limits of temperature and hydrochemical indicators (pH and dGH). In aquarium design, hiding places play a key role. Otherwise, the catfish is very undemanding and can adapt to various conditions. High water quality directly depends on regular aquarium maintenance (including partial water changes and waste removal) and the uninterrupted operation of equipment, primarily the filtration system.

This species is omnivorous. Its diet should be varied, including dry, frozen, and live foods, as well as fresh pieces of vegetables and fruits. It is important to note that all foods must be sinking, as the fish does not rise to the water surface to feed.

Cases of breeding these catfish are not uncommon. When the breeding season begins, males begin to jealously guard their territory, while actively courting females. As soon as the female shows readiness to spawn, the pair retires to a shelter to lay eggs. After spawning, the female leaves the clutch site, and the male remains to protect and care for the eggs. The male's parental instincts fade with the appearance of fry.

Most health problems in fish often arise from unsuitable keeping conditions. Maintaining a stable and comfortable habitat is a key factor for successful keeping. If symptoms of illness appear, the first step is to check the water quality. If deviations are found, it is important to take immediate measures to eliminate them. If the symptoms do not disappear or worsen, medicinal treatment may be required.

When choosing Peckoltia, attention should be paid to the fish's activity and the condition of its skin. Healthy individuals should be mobile, without visible damage, ulcers, white plaque, or signs of emaciation, where the abdomen appears sunken. It is important to consider that these are nocturnal fish, so in the store they may be inactive and hide in shelters, which is normal behavior. — Avoid buying fish that show signs of timidity or apathy, if they lie motionless on the bottom or near the water surface. — Check the cleanliness of the fins and the absence of signs of rot or damage on them. — Ask the seller what the specific individual eats, as adaptation to dry foods in captivity can vary individually.
