🐟 Glass Catfish (Kryptopterus vitreolus)
Shimmering See-Through Schooling Fish • A Graceful Midwater School • Happiest in a Group of Six or More
 
📋 The Glass Catfish, also called the Ghost Catfish or Phantom Catfish, is one of the most mesmerising fish in the hobby: a fully transparent body that lets you see its skeleton and internal organs, gliding in a graceful, shimmering school. Its see-through look is entirely natural. It is never dyed and doesn't need to be, unlike the unrelated "painted glass fish" (Parambassis ranga) sometimes sold in the trade.
Glass Catfish are true schoolers. In the wild they gather in groups of dozens to over a hundred, always facing into the current together, so they're at their best in a group of six or more, where they feed confidently, swim openly, and live for years. Kept alone or in very small groups they can become stressed and stop eating, which is why we always recommend six or more. Add dense planting, gentle flow, and clean, stable water, and they make a stunning centrepiece for a peaceful planted tank.
