The fish arrived healthy and active. It has adapted well to the 40-gallon tank with a mix of corals. It’s not overly aggressive but does defend its territory. Good for intermediate reef keepers.
Lily Lewis –
We’ve had this clownfish for three months. It’s vibrant and stays in its preferred area. It doesn’t harm other fish, though it does chase smaller fish occasionally.

Perfect addition to a reef tank. The red saddleback pattern is striking. It’s active and seems to thrive in a well-maintained environment.
