Approx. 2" - 2.5" Glass Catfish lack body pigment and are transparent.   They have a slender body, an anal fin that extends almost from the head to the forked caudal fin, two long barbels, and usually only grow to about 3″ in length.   Most of their organs are located towards the head and although they are transparent, they have an iridescent rainbow color when the light strikes them at the right angle. Glass Catfish are a timid, non-aggressive, mid water swimming species that prefer hiding in the darker areas of the river.  They are frequently collected while hiding under logs, elevated rock outcroppings, and in the shadows of overhanging vegetation in areas with a good amount of water movement. In an aquarium environment, they need a densely planted tank with a lot of swimming area, a gentle amount of current, and some driftwood roots for shelter. A generous growth of aquatic plants is imperative to their well being, and floating plants should also be included in their tank to filter out bright lighting. In their natural habitat they are found in small schools, and should be kept with at least 5 or 6 of their own kind in a community tank setting with other peaceful fish of the same size. They do well with the smaller tetras, Corydoras, etc. Glass catfish are relatively delicate and are extremely sensitive to changes in water quality and pH. They do best in soft (less than 10 ° dGH), slightly acidic (pH 6.5) water, at a temperature around 77 °F. A good quality filter that provides some water movement is necessary for this species. Glass Catfish in an aquarium environment are reputedly finicky eaters however, they will accept live, frozen, or freeze dried bloodworms, tubifex, brine shrimp, and mosquito larvae. They can be weaned to accept flake foods. Minimum Tank Size: 10 gallons Care Level: Moderate Temperament: Peaceful Water Conditions: 75-80° F, KH 8-12, pH 6.5-7.0 Max.
