Kryptopterus vitreolus is a small, transparent-bodied, freshwater-dwelling catfish with two long sensory barbels. Standard lengths for mature fish may range up to 8 cm (3.1 in), but usually only reach around 6.5 cm (2.6 in) in total length. [2] Their bodies are transparent because, like all catfish, they lack scales.
Despite this name, only three described species have clearly transparent bodies: K. minor, K. piperatus and K. vitreolus. [2] Most significant among these is the ghost catfish (K. vitreolus), which is the "glass catfish" most often seen in the aquarium fish trade.
K. bicirrhis reaches a significantly larger size, up to 15 cm (5.9 in) standard length, [6] and most of its body is not clearly transparent (only obviously transparent around the head). [2] [3] [4] The body of K. bicirrhis is mostly opaque and light greyish. [2] [3] [4] When struck by light, it has an iridescence, and it turns milky white as it ...
Pterygoplichthys anisitsi [1] [2] also known as the Paraná sailfin catfish, southern sailfin catfish, is a species of catfish in the family Loricariidae. [3] Its natural range is the middle Paraná and Uruguay River basins of south-central South America, [4] but it has been introduced to North America and South Asia, probably via the pet trade.
Members of the family Loricariidae are commonly referred to as loricariids, suckermouth catfishes, armoured catfish, or suckermouth armoured catfish. [4] The name "plecostomus", and its shortened forms "pleco" and "plec", are used for many Loricariidae, since Plecostomus plecostomus (now called Hypostomus plecostomus) was one of the first loricariid species imported for the fish-keeping hobby.
Asterophysus batrachus, the gulper catfish or ogre catfish, is a species of catfish (order Siluriformes) of the family Auchenipteridae. It is native to the Rio Negro and Orinoco basins in Brazil , Colombia and Venezuela , [ 2 ] [ 3 ] where mostly found in slow-moving waters with many submerged structures. [ 4 ]
Many of the members of this family are small, cryptically colored fish with tuberculate skin. [5] Erethistids are distinguished from sisorids by having a pectoral girdle with a long coracoid process that extends well beyond the base of the pectoral fin; this structure can be felt through the skin in all genera and is visible externally in all genera except Pseudolaguvia.
Wallago attu, the boal or helicopter catfish is a freshwater catfish of the family Siluridae, native to South and Southeast Asia. W. attu is found in large rivers and lakes in two geographically disconnected regions (disjunct distribution), with one population living over much of the Indian Subcontinent and the other in parts of Southeast Asia.
