🐡 Glass Catfish Kryptopterus vitreus

The Glass Catfish (Kryptopterus vitreus) is a moderate-care, peaceful species from Southeast Asia. Adults reach roughly 4", so plan on a minimum tank of 30 gallons. Keep the water between 75–82°F with a pH of 6–7.5. This is a schooling fish — keep a group of at least 6 so it feels secure and colors up. As a carnivore, it does best on a varied diet appropriate to its feeding style.
