Identification Tips

1. 1

   Opercular Spot

   Look for the distinct black spot on the gill cover with a bright red or orange margin. This is the most reliable distinguishing feature.

   Observe the iridescent blue-green wavy lines on the operculum and cheek, and the overall vibrant, mottled coloration with iridescent spots.

3. 3
