The Blue Damsel adds a lot of visual interest to my reef tank. The colour is vibrant and it’s very active. I had to be careful with placement to avoid conflicts with other fish, but overall it’s a great addition.
Anna Duncan –
Beautiful fish with strong colours. The male developed orange on his tail after a few months. I keep it with other peaceful reef fish and it’s not aggressive as long as there’s enough space.

Highly recommended for reef enthusiasts. The blue colour stands out in the tank. It’s hardy and stays healthy even in a busy environment. Just make sure to avoid keeping it with very small or shy fish.
