Croaking Gourami Identification Guide

Key identification features

  • Small, slender body around 2-2.5 inches long
  • Mottled brown-and-tan camouflage pattern over the body
  • One or more horizontal dark stripes or rows of iridescent blue-green spangled spots along the flanks
  • Rounded dorsal, anal, and caudal fins typical of smaller gouramis, sometimes edged with a thin reddish or orange margin in males
  • A dark stripe often runs through the eye, extending the body pattern onto the head
  • Body shape is slim and slightly elongated compared to deeper-bodied gouramis, with a gently pointed snout
  • Capable of producing an audible croaking sound during courtship and territorial display, often with visible throat movement

Common look-alikes

  • Sparkling gourami: smaller still, with denser iridescent blue spangling covering more of the body and a shorter, less continuous stripe
  • Pearl gourami: considerably larger, with a bold unbroken lateral stripe and pearly spotting covering the entire body

Where you'll see one

Croaking gouramis live in densely vegetated, slow-moving streams, ditches, and swamps across Thailand, Cambodia, Vietnam, and Malaysia, typically in shallow water with heavy plant cover close to the surface.
