A highly unique, completely transparent catfish from Thailand. Unlike most catfish, they are mid-water swimmers that require being kept in schools to feel secure. They are incredibly peaceful and easily outcompeted for food. They require stable water parameters and dim lighting or shaded areas provided by floating plants.

Glass Catfish Care Guide Summary
The Glass Catfish, scientifically known as Kryptopterus vitreolus, belongs to the Catfish family group. Adults reach a maximum size of approximately 8 cm and have a compressed body shape with a moderate growth rate. Classified as peaceful, this species primarily occupies the mid-level zone of the aquarium and produces a low level of biological waste.
To thrive, the Glass Catfish requires a freshwater only aquarium with a minimum volume of 110 litres and a tank length of at least 90 cm. Water temperature should be maintained between 24°C and 28°C, with a pH range of 6–7 and a general hardness of 1–10 dGH. A moderate water flow is preferred.
The Glass Catfish is a rewarding species to keep, provided its core environmental needs are met. The Glass Catfish is typically available in one standard form.
Glass Catfish Habitat Setup
When setting up an aquarium for the Glass Catfish, a moderate water flow best suits their natural preferences. Because this species occupies the mid-level zone, the aquarium layout should prioritise open swimming space in the centre of the tank for free movement. Useful additions include dense planting to provide cover, break sightlines, and reduce stress and floating plants to diffuse overhead light and create shaded areas.
Glass Catfish Compatibility Notes
Classified as peaceful, the Glass Catfish is a social species that requires the company of its own kind to thrive. When choosing tankmates, boisterous or fast-moving tankmates may cause this species undue stress. Selecting tankmates that favour different water layers from the mid-level zone can help reduce competition and territorial overlap.

Ghost Shrimp
Palaemonetes paludosus
A completely transparent freshwater shrimp native to the southeastern United States. While frequently sold as inexpensive feeder animals, they make fascinating, active scavengers for nano and peaceful community tanks. They tirelessly consume uneaten food and detritus but have a relatively short lifespan of 1 to 2 years.
Iridescent Shark
Pangasianodon hypophthalmus
The Iridescent Shark is not a true shark, but a highly active, schooling catfish native to Southeast Asia. While frequently sold as tiny juveniles, they are notorious 'tank busters' that grow to massive sizes. They are extremely skittish and easily spooked, often injuring themselves by crashing into aquarium glass. They are best suited for heated indoor ponds or massive custom aquariums.
Striped Raphael Catfish
Platydoras armatulus
A highly robust, armored catfish native to the Amazon and Orinoco basins. Famous for their ability to produce audible squeaking or grunting sounds when distressed or defending territory. They are nocturnal scavengers that spend most of the day hiding in driftwood or caves. Note: Their rigid pectoral spines can easily become tangled in standard aquarium nets.
Siamese Algae Eater
Crossocheilus oblongus
Famous for being one of the few freshwater fish that actively consumes Black Beard Algae (BBA). A torpedo-shaped, active bottom-to-midwater swimmer native to Southeast Asian streams. True Siamese Algae Eaters feature a distinct black horizontal stripe that extends all the way through the tail fin. As they mature, they can become lazy, preferring prepared foods over algae, and may occasionally chase other bottom dwellers.
Japanese Ricefish (Medaka)
Oryzias latipes
A hardy, small, and colorful fish native to East Asia. Extremely popular in the outdoor pond hobby and nano aquariums. They are 'amphidromous' (tolerant of salinity changes) and can survive a wide range of temperatures, making them excellent tub/pond fish. They are surface dwellers that look best when viewed from above (top-down).
White Cloud Mountain Minnow
Tanichthys albonubes
A hardy, peaceful, and active schooling fish famous for its ability to thrive in unheated, sub-tropical aquariums. Native to the mountain streams of China, they feature a bronze body with a striking neon-like lateral stripe and red-tipped fins. They are strictly schooling fish and must be kept in groups to feel secure and display their best colors.
