Barboach is a blue and gray loach-like Pokémon with a whiskery blue face and three fins. All of its fins are uchiwa fan-shaped(the dorsal, pelvic, anal and tail fin), while only the dorsal, pelvic and anal fins have black spots on them. All across it's side there is a zigzag black line. Barboach does not have any visible pectoral fins though.
Barboach is actually derived from the dojo loach, a type of catfish-relative fish with many characteristics with the genus such as; burying themselves to hide from view, using their whiskers to detect their surroundings, secretion of a slimy substance and the ability to encase themselves in mud.
Although, they make look more like the false eel called as 'bichir'. Like loaches, bichirs have barbels and relies on smell replacing its poor eyesight.
Barboach is a combination of barb (referring to the barbs around its mouth) or barbel and loach.
