About the Bluestreak Cleaner Wrasse
A staple of the wild coral reef, Labroides dimidiatus sets up permanent 'cleaning stations' where larger fish queue up to be groomed. Their torpedo-like bodies feature a striking blue and white base bisected by a bold black lateral stripe that widens towards the tail. While they are incredibly fascinating to observe as they dance to attract clients, they demand specialised care and frequent feeding in the home aquarium to thrive long-term.
