Tank Size: Oto catfish are small and should be kept in a tank of at least 10 gallons, although a larger tank is better for a group of otos. Water Parameters: Maintain stable water conditions with a temperature of 72-78°F (22-26°C), a pH level around 6.5-7.5, and soft to moderately hard water. Otos are sensitive to poor water quality, so regular water changes are essential. Filtration: Use gentle filtration to avoid strong currents, as otos come from slow-moving waters. Provide good water flow, but avoid sucking them into the filter intake. Decor: Include live plants, driftwood, and hiding spots. Otos are herbivorous and graze on surfaces, including the biofilm that can grow on decor and plant leaves. Tank Mates: Oto catfish are peaceful and should be kept with other non-aggressive species. They do well in a community tank with other small, peaceful fish. Diet: Otos are herbivores and primarily feed on algae and biofilm. Supplement their diet with algae wafers, blanched vegetables like zucchini, and high-quality sinking pellets.
