Species Interaction

Aquarium, Snorkeling & Diving

The Silverstreak Wrasse are popular among marine aquarium enthusiasts due to their striking coloration and active behaviour. However, they are known to be territorial and can be aggressive towards other fish that invade their space. They can be a delight to snorkelers and divers as they are often seen near coral reefs and rocky areas in shallow to moderate depths. With their striking blue-green coloration and vivid stripes, they are easily spotted and can make for great photo opportunities.
