Keith Anderson –
The Kato Fairy Wrasse has become a highlight in my reef tank. The colour change in the male is stunning, especially after a few months. It’s active but not aggressive and doesn’t bother other fish. I appreciate the peaceful nature and how it fits well with the rockwork.
Adrian Wilkins –
Beautiful fish with vibrant colours. It’s active and shows interest in the surroundings. I’ve had it for six months and it’s still showing good health and natural behaviour. A great addition to a well-established reef setup.
Eric Walsh –
The fish arrived healthy and has adapted quickly. The red and orange hues are very striking, especially when it displays its fins. I’m happy with the peaceful nature and how it coexists with other reef species.
