About Upside-Down Catfish
The scientific name of the upside-down catfish is Synodontis nigriventris. It is a small fish, usually growing up to 3.5 inches long. This fish is native to Africa, where it lives in rivers and lakes. It likes to swim with its belly facing the water surface. This helps it eat food from the top of the water.
These fish are peaceful and like to live in groups. They are perfect for home aquariums because they are easy to care for if you follow some basic steps.
How Many Upside-Down Catfish Should You Keep?
Upside-down catfish are social animals. They like to live in groups. It is best to keep at least three or more together. If you keep only one or two, they may feel scared or lonely. When in groups, they swim and play more actively.
If you keep them with very aggressive fish, they may hide a lot. So, choose calm tank mates. Good tank mates help your catfish feel safe and happy.
Tank Setup for Upside-Down Catfish
Setting up the right tank is important for upside-down catfish care. Here are some key points for the tank:
- Tank Size: A 20-gallon tank is good for a small group of these fish.
- Plants: They like tanks with many plants. Plants give hiding spots and make them feel safe.
- Hiding Places: Use rocks, driftwood, and caves. These places help the fish hide if they feel scared.
- Water Conditions: The water should be clean and fresh. Keep the water temperature between 72°F and 82°F.
- Water pH: They prefer water that is slightly acidic to neutral. A pH between 6.0 and 7.5 is good.
- Water Hardness: Soft to moderately hard water is best.
Remember, upside-down catfish are sensitive to water quality. Change the water regularly to keep nitrate levels low. A weekly partial water change of 20-30% works well.
