Bluestreak Cleaner Wrasse
Labroides dimidiatusAlso known as Blue-banded Cleaner Wrasse, Cleaner Wrasse, Bridled Beauty
Bluestreak cleaner wrasses operate active cleaning stations on Indo-Pacific coral reefs, performing a distinctive dancing motion to attract prospective client fish. They fearlessly enter the gills and mouths of large predatory fish to consume external parasites and dead skin tissue. Beyond their vital ecological role, these small fish have demonstrated self-recognition in laboratory mirror tests, highlighting surprising cognitive abilities.

Responsible observation
- Observing Stations: Approach coral heads slowly to watch client fish line up quietly for service.

- Spotting Mimics: Look closely for bluenose blennies that copy the wrasse color pattern to bite clients.
