Asian Glass Catfish
Kryptopterus vitreolus is a curious species of schooling catfish from Thailand. In life, these fish are completely see-through, with all their bones visible, making them a standout species in any tank. These catfish reach about 3-3.5″ long and should be housed in groups, with at least 5-6 being recommended. Glass cats are quite shy so they fare better with smaller, laid-back tankmates. They also appreciate subdued lighting or the addition of floating plants as they tend to hide away from bright light. Overall these are one of the most unique-looking community fish out there, sure to draw attention to any tank they’re in!
These specimens range from about 1.5″ long to 2.5″.

The glass catfish are absolutely stunning. They look like tiny transparent creatures with visible bones. I kept them in a 20-gallon tank with some floating plants and dim lighting. They’ve settled in well and swim together in groups. Very peaceful and unique.

I bought these for my community tank. They’re shy at first but after a week they started swimming around more. I added java fern and kept the lights low. They look beautiful and don’t bother other fish.

These fish are a visual highlight. I’ve never seen anything so transparent and delicate. They stay near the bottom and hide under plants, which is normal. After a few days they began to swim in groups. Great for a visually interesting tank.
