The fish commonly sold in the aquarim trade was misidentified for long years as K. bicirrhis. The actual fish turned out to be a completely new species described by Ng and Kottelat in 2013. Our glass catfish is a smaller, prettier, completely transparent fish, while the original bicirrhis is a bigger and opaque colored animal, which was probably never present in the aquarium hobby. The glass catfish feeds on small animals like worms and larvae. It's diet is mainly carnivorous but means no danger to the inhabitants of the fish tank - it can't eat anything bigger than a fry. You can feed it with high protein pellets or quality frozen foods. The glass catfish is timid and a slow feeder, does not compete well with bigger or more voracious fish. Keep the glass catfish in groups, it's not only preferred by the fish but the best way to show off their beauty. The glass catfish needs some protected, heavily vegetated space. Fortunately it's not a big challange in a planted tank. They like to swim under floating plants. Soft, acidic water is preferable. Do not add this fish until the nitrogen cycle is fully matured.
