Sunset Wrasse (Thalassoma Lutescens)
Sunset Wrasse (Thalassoma Lutescens)
The Sunset Wrasse (Thalassoma lutescens), also known as the Banana Wrasse, is an energetic and brightly colored marine fish native to the Indo-Pacific. Reaching up to 25 to 30 cm in home aquariums, this active swimmer showcases vivid yellow-green hues in its initial phase, transforming into an array of greenish-blue with pink and red markings as a terminal phase male.
Ideal for large fish-only setups, this robust species thrives in aquariums of at least 473.2 to 567.8 L with a deep, fine-grained sand bed and a secure lid. As a natural carnivore with a high metabolism, it requires a diverse diet of meaty marine foods and pairs best with bold, similarly semi-aggressive tankmates.
