Mexican Wrasse

Why We Like It:

Vibrant and energetic, the Mexican Wrasse displays bold red and green coloration with classic Thalassoma speed and confidence. Best suited to predator or FOWLR systems, it’s hardy and active but not reef-safe with inverts. A great choice for lively, larger tanks that can handle its attitude.
