Cobra / Snakeskin
A variant of Guppy (Poecilia reticulata)

A body-pattern line covered in fine maze-like 'snakeskin' vermiculation over the body and fins. A man-made pattern strain bred for the intricate reticulation.
Keeper tips for this variant
Pattern quality concentrates in the line, so to keep crisp snakeskin buy a trio from one breeder rather than mixing in random fancy stock.
