Synodontis angelicus, commonly known as the Angelicus Catfish or the Angel Catfish, is a species of freshwater catfish belonging to the family Mochokidae. This species is native to the Congo River basin in Central Africa, specifically found in the Democratic Republic of Congo. It's popular among aquarium enthusiasts due to its striking appearance, unique behaviors, and relatively manageable care requirements.

Here are some key characteristics and information about Synodontis angelicus:

1. Appearance: Synodontis angelicus showcases a distinctive appearance with a beautiful contrast of colors and patterns. It has a deep, laterally compressed body covered in a mixture of dark brown and beige bands, which resemble a marbled or camouflaged pattern. Its dorsal and caudal fins are adorned with attractive white edges.

2. Size: This catfish species can grow to a size of around 8 to 10 inches (20 to 25 cm) in captivity.

3. Habitat: In the wild, Synodontis angelicus inhabits slow-moving or standing waters, including river channels, floodplains, and swamps in the Congo River basin. It's often found in areas with submerged vegetation or hiding spots, such as tree roots and submerged branches.

4. Behavior: Angelicus Catfish are generally peaceful and nocturnal creatures. They are known to be good tankmates for many other community fish species. They are bottom-dwellers, and they'll spend much of their time exploring and scavenging the substrate for food.

5. Diet: In the wild, these catfish feed on various small invertebrates, insects, and plant matter. In captivity, they can be fed a diet of high-quality sinking pellets, frozen or live foods, and occasional vegetable matter.

6. Tank Requirements: A well-maintained aquarium with plenty of hiding spots, such as caves, driftwood, and plants, is ideal for Synodontis angelicus. They appreciate dim lighting due to their nocturnal nature. Water parameters should be kept relatively stable with a temperature around 75-80°F (24-27°C), a pH range of 6.5-7.5, and moderate water flow.

7. Breeding: Breeding Synodontis angelicus in captivity is more challenging compared to other catfish species. They are known to lay their eggs on various surfaces, but detailed breeding requirements can be complex and difficult to replicate in a home aquarium.

Remember that proper research and care are essential before introducing any fish into your aquarium. If you're considering keeping Synodontis angelicus, ensure that your tank setup meets their specific needs to ensure their well-being and longevity.
