Identification Tips

1. 1

   Coloration

   The intense magenta to purple body color is the most distinguishing feature. No other Red Sea dottyback shares this exact hue.

2. 2

   Eye Stripe

   The distinct black stripe running through the eye is a key identifier, though its intensity can vary slightly.

3. 3

   Geographic Range

   Its endemic status to the Red Sea helps differentiate it from similar-looking species found in other Indo-Pacific regions.

4. 4

   Size and Shape

   Its relatively small, elongated body (up to 6.5 cm / 2.5 inches) helps distinguish it from larger or differently shaped dottybacks.
