Thai Glass Catfish - (No Online Purchases)

Scientific Name: Kryptopterus vitreolus

Description: A fascinating and peaceful freshwater catfish recognised for its almost completely transparent body, allowing its backbone and internal structures to be seen. Thai Glass Catfish have a slender body, long barbels and a delicate, shimmering appearance. These unusual fish are active, social swimmers that prefer to remain in groups, often hovering together in the middle levels of the aquarium. Their unique appearance makes them a beautiful addition to peaceful, well-planted community aquariums.

Origin: Southeast Asia, particularly Thailand, where they inhabit slow-moving rivers, streams and freshwater waterways.

pH: Approximately 6.0–7.5

Temperature: Around 23–27°C

Adult Size: Approximately 6–8 cm

Lifespan: Approximately 5–8 years under suitable aquarium conditions.

Food: Carnivorous. Feed a varied diet of small frozen or live foods such as bloodworms, brine shrimp, daphnia and mosquito larvae. May also accept quality small sinking or slow-sinking pellets and flakes once accustomed to aquarium feeding. Ensure food reaches them in the middle water levels.

Compatibility: Extremely peaceful and best kept in groups of at least six, preferably eight or more, to encourage natural schooling behaviour and reduce stress. Suitable tank mates include peaceful Tetras, Rasboras, small Gouramis, Corydoras and other non-aggressive community fish. Avoid large, aggressive or overly active species that may intimidate them or compete aggressively for food.

Habitat: A mature, well-established freshwater aquarium with plenty of aquatic plants, driftwood and shaded areas for shelter. Thai Glass Catfish prefer clean, stable water with gentle to moderate flow and open swimming areas. Floating plants and subdued lighting help them feel secure.  They are sensitive to sudden changes in water parameters, making regular water changes and excellent filtration essential.
