Pantodon buchholzi is a Pantodontidae from 非洲. Its calm temperament and broad diet make it one of the more forgiving residents of a community tank. It swims in mid-water. Adults reach 4–8 cm. Keep in a group of 4–6 for natural behaviour. Stable water, regular partial changes and a varied diet cover nearly everything it needs. Maintain 20–26 °C at pH 6.5–7.5. A rewarding species for the aquarist who reads before buying.
