Glass catfish

(Kryptopterus minor)


Category: Fish



These unique, transparent catfish are endemic to Thailand and commonly seen in the aquarium trade. Their lack of scales (like all catfish) and body pigment accounts for their transparency and it is even possible to see their tiny heart beating with a magnifying glass. Unlike most other catfish, they prefer to swim in mid- to upper- water levels.

Because the scales of silvery fish that capture and reflect light so beautifully in the water function the same way on your lips.
