A see-through catfish - Kryptopterus vitrelous

The bizarre, transparent glass catfish Kryptopterus vitrelous (often incorrectly identified as K. bicirrhis and K. minor) was only given a scientific name in 2013. They are native to slow-moving coastal river basins in Peninsular Thailand, are rarely bred in captivity, and are collected in large numbers from the wild. Glass catfish are a peaceful schooling species and a great addition to an established, well planted, tank with small tank mates such as eyespot rasboras, harlequin rasboras, and kuhli loaches. They grow to 6.5 cm and are suited to temperatures of 20 to 26°C and pH’s of 4 to 7
