The Cleaner Wrasse, also known as the Bluestreak Cleaner Wrasse, is a popular and beneficial species of saltwater fish that is highly sought after for its ability to clean other fish of parasites and dead skin. These fish are native to the Indo-Pacific region and are a favorite among reef hobbyists.
 
Cleaner Wrasse require a moderate-sized tank of at least 30 gallons with plenty of swimming space and hiding places. They are relatively hardy and can adapt to a variety of water conditions, but they prefer a stable environment with consistent water parameters and a salinity level between 1.020-1.025.
 
The Cleaner Wrasse can grow up to 4 inches in length and has a peaceful temperament, making it suitable for a community tank with other non-aggressive fish. They are generally not aggressive towards other fish or invertebrates, but may become territorial towards other Cleaner Wrasse or similar-looking fish.
 
These fish are omnivores and require a varied diet of both meaty and plant-based foods. They are particularly fond of live and frozen foods such as brine shrimp and mysis shrimp. In addition to their regular diet, they will also feed on parasites and dead skin from other fish in the aquarium.
