Spotted Synodontis

As a classic representative of the order Siluriformes, the Spotted Synodontis possesses all their inherent characteristics. Although various color variations exist, specimens from yellowish to brownish hues, covered with large dark spots, are most commonly found. A prominent fin with sharp spines is located on its back, so when transporting the fish, it is recommended to use rigid glass or plastic containers, avoiding soft bags.

The species is widely distributed in West and Central Africa, including the Senegal, Gambia, Niger, and Volta river basins, as well as Lake Chad. It inhabits river systems with varying currents, preferring the bottom layers of water. In its natural environment, it leads a secretive lifestyle, often staying among snags, rocks, and other natural shelters that provide protection during daylight hours.

In most cases, the Spotted Synodontis successfully coexists with various species of peaceful fish, regardless of their size. However, it should be noted that due to the significant size of the catfish itself, smaller tankmates may experience some stress. These fish can be kept both in groups of their own kind and individually.

The fish demonstrates a high degree of adaptation to various water parameters, making no special demands on its composition or quality. Adult specimens, however, produce a significant amount of waste, so to reduce the load on the biological filter, it is advisable to change about 20% of the water volume every two weeks. Successful keeping requires a sufficiently large aquarium — at least 300 liters for adult specimens, necessarily equipped with shelters such as grottoes or caves. Natural wood, whether snags or roots, will serve well as decorations. In addition, the aquarium must be equipped with a powerful filtration system that provides not only effective water purification but also creates a moderate current, imitating natural conditions. Special lighting is not mandatory, as synodontis prefer to hide in shelters during daylight hours.

The diet of this fish can include all types of dry commercial foods, such as flakes and granules, as well as plant-based foods, live and frozen foods. Despite its omnivorous nature, it is important to ensure that meat products (e.g., tubifex worms, bloodworms, brine shrimp) constitute at least half of its daily diet. This is necessary to meet the fish's protein requirements, which are critically important for its full development.

Sexual differences in these fish are weakly expressed, making them difficult to determine. Breeding the Spotted Synodontis in home aquariums has not yet been successful, so all available specimens are either caught in natural conditions or raised in specialized fish farms.

The fish exhibits high resistance to diseases when kept under proper conditions. The main health problems arise from poor water quality, accumulation of organic waste, and high nitrate levels. Sensitivity to conditions manifests as weakened immunity, making the individual vulnerable to bacterial infections and ectoparasites. For prevention, it is necessary to maintain water cleanliness, ensure powerful filtration, and regular partial water changes.

When choosing, attention should be paid to the fish's activity in the evening, as daytime passivity is normal. Healthy individuals should have clean skin without white spots, ulcers, or fin damage, and show no signs of emaciation. Avoid purchasing fish with a sunken belly or an unnaturally bloated abdomen. Given the presence of sharp spines on the fins, transportation is recommended in rigid containers to avoid injuring the fish and damaging bags.
