Delightful Synodontis Upside-Down Catfish | Playful Community Favorite
Bring a smile to your face every time you look at your tank with the Delightful Synodontis Upside-Down Catfish for sale. As one of the most popular and beloved dwarf catfish in the hobby, their signature upside-down swimming style isn’t just a quirk—it’s a natural behavior evolved to help them graze on the undersides of leaves and structures in the wild.
These captivating fish are peaceful, highly adaptable, and perfect for community aquariums. While they can be kept singly, they truly thrive and display much more active, playful behavior when kept in small groups.
Approximate size: 1.5″ – 2″ (Unsexed)
