Identification Tips

1. 1

   Body Shape and Size

   Look for a slender, elongated body, typically reaching up to 16 cm (6.3 inches) in length, though usually smaller.

2. 2

   Coloration and Patterns

   Observe the highly variable background color (grey, brown, green) and the presence of mottling or speckles. Crucially, look for the dark spot at the base of the caudal fin and sometimes on the dorsal fin. Breeding males will have more intense and distinct patterns.

3. 3

   Snout and Mouth

   Note the pointed snout and relatively small, protractile mouth with thick lips, characteristic of wrasses.

4. 4

   Fin Structure

   Examine the single, long dorsal fin and the rounded caudal fin.
