Description
The Striped Glass Catfish (Kryptopterus macrocephalus) is a lesser-known yet visually intriguing freshwater species native to the slow-moving, tannin-stained waters of Southeast Asia. Not to be confused with the more transparent Ghost Glass Catfish (Kryptopterus vitreolus), this species is slightly more robust and displays faint vertical striping along its semi-transparent body. Peaceful and schooling by nature, the Striped Glass Catfish is well suited to mature, dimly lit aquariums that replicate its natural blackwater habitat.

Diet for the Striped Glass Catfish
Carnivorous and somewhat shy during feeding, this species prefers small, live or frozen foods:
Aquarium Setup Striped Glass Catfish
Aquarium Filtration
Use a high-efficiency canister or sponge filter that provides gentle flow. Water should be clean but not turbulent, as the species comes from calm waters.
Aquarium Plants
Live plants are highly recommended. Use species like Java fern, Cryptocoryne, and floating plants such as Amazon frogbit to diffuse light and replicate blackwater conditions.
Aquarium Lighting
Low to subdued lighting is ideal. Use dimmable LEDs or shade parts of the tank with floating plants to reduce stress and highlight their translucent features.
Aquarium Heating
Maintain water temperatures between 24°C and 27°C. Ensure stability with a reliable heater and avoid sudden fluctuations.
Aquarium Substrate
Dark, soft substrates such as sand or fine gravel enhance their colouring and reduce stress. Avoid sharp or reflective materials.
Aquarium Decorations
Use driftwood, leaf litter, and smooth stones to create a natural blackwater environment. Provide ample hiding spots and shaded zones to support their schooling and resting behaviours.
