Spotted Synodontis

As a typical catfish, the spotted synodontis has all the features characteristic of the group. Though various colour forms exist, you will most often see specimens ranging from yellowish to brown, covered with large dark spots. The back has a prominent fin with sharp spines; when transporting the fish, use hard glass or plastic containers and avoid soft bags.

The species is widespread in West and Central Africa, including the basins of the Senegal, Gambia, Niger, and Volta rivers, as well as Lake Chad. It inhabits river systems with varying water flow, preferring the bottom layers. In the wild, it is reclusive, living among driftwood, rocks, and other natural shelters that provide daytime protection.

In most cases, the spotted synodontis coexists successfully with various peaceful fish species, regardless of their size. However, because of the catfish's considerable size, small tank mates may experience some stress. You can keep these fish in groups with their own kind or singly.

The fish shows a high degree of adaptation to various water parameters and makes no special demands on water composition or quality. Adult fish, however, produce substantial waste, so to reduce the load on the biological filter, change about 20% of the water every two weeks. Successful keeping requires a fairly large tank — at least 300 litres for adults — with hiding places such as grottoes or caves. Natural wood such as driftwood or roots makes good decor. The tank must also have a powerful filtration system that not only cleans the water effectively but also creates moderate water flow, mimicking natural conditions. Special lighting is not necessary, as during the day spotted synodontis prefer to hide in shelters.

The diet may include all types of commercial dry foods such as flakes and pellets, as well as plant matter and live and frozen foods. Despite omnivory, it is important to ensure that meat products (for example, tubifex, bloodworm, and brine shrimp) make up at least half of the daily diet. This is necessary to meet the fish's protein requirements, which are critical for its proper development.

Sexual differences in these fish are poorly expressed, making them difficult to distinguish. Breeding the spotted synodontis in home aquariums has not yet been successful, so all available specimens are either wild-caught or raised in specialized fish farms.

The fish is highly resistant to disease when kept in proper conditions. Major health problems arise from poor water quality, accumulation of organic waste, and high nitrate levels. Sensitivity to conditions manifests as weakened immunity, making the fish vulnerable to bacterial infections and ectoparasites. Prevention requires maintaining clean water, providing powerful filtration, and regular partial water changes.

When selecting a fish, pay attention to its activity in the evening, since daytime inactivity is normal. Healthy individuals should have clean skin without white spots, sores, or fin damage, and show no signs of emaciation. Avoid fish with a sunken belly or an unusually swollen abdomen. Given the sharp spines on the fins, transport the fish in hard containers to avoid injury to the fish and damage to bags.
