Added a male Lyretail Anthias to my 75-gallon reef tank. It’s active and colorful, and has not shown aggression toward other fish. The fish settles in well and adds visual interest. Good for intermediate reef keepers.

The fish is vibrant and active. I noticed it tends to stay near the back of the tank, so I adjusted the layout to give it more space. Works well with corals and other peaceful fish.
