Keeping Upside-Down Catfish involves providing a peaceful, well-planted tank with dim lighting, hiding spots like driftwood and caves, and strong filtration, as they are social, nocturnal omnivores that prefer groups and clean, warm (24-28°C) water with a slightly acidic to neutral pH (6.0-7.5). Feed them sinking pellets and occasional live/frozen foods, and ensure plenty of surfaces (leaves, rocks) for them to hang upside down on, especially in areas with current.
