About the Upside Down Catfish
Name: Upside Down Catfish (Synodontis nigriventris)
Max Size: Upside Down Catfish are relatively small and typically reach around 3-4 inches in length when fully grown.
Water Parameters: They prefer slightly acidic to neutral water conditions with a pH range of 6.5-7.5. The temperature should be maintained between 75-82Β°F (24-28Β°C) to replicate their native tropical environment.
Diet: Upside Down Catfish are omnivorous and have a varied diet. In the wild, they feed on small aquatic invertebrates, insects, and algae. In the aquarium, they readily accept high-quality sinking pellets, flakes, and frozen foods like bloodworms and brine shrimp.
Temperament: Upside Down Catfish are peaceful and generally get along well with other community fish. They have a unique swimming behavior of swimming upside down near the surface, which adds a distinctive touch to your aquarium.
Schooling or Non-Schooling Fish: Upside Down Catfish are non-schooling fish but tend to be more active and comfortable when kept in groups of three or more individuals.
Possible Types of Tank Mates: They are compatible with a wide variety of peaceful community fish, such as tetras, gouramis, rasboras, and other small catfish species. Avoid keeping them with aggressive or larger predatory fish that may see them as potential prey.
Tank Setup: Provide a well-decorated aquarium with ample hiding spots using driftwood, rocks, and live plants. Upside Down Catfish appreciate plenty of open swimming space near the surface, where they can display their unique swimming behavior. Ensure the tank has a tight-fitting lid as these catfish may jump when startled.
Behavior: True to their name, Upside Down Catfish display an intriguing behavior of swimming upside down near the water's surface. They have evolved to have an inverted mouth that allows them to feed on food particles at the surface, making them efficient at consuming floating food.
Fun Fact: Upside Down Catfish are known for their peculiar behavior of swimming upside down, but they are not the only catfish species to do this. Several other fish, like the Synodontis batensoda and Synodontis contractus, also exhibit similar swimming behaviors. This adaptation has evolved as a way to exploit food resources near the water's surface, providing a fascinating sight for aquarium enthusiasts.
