This clownfish is a stunning addition to my 120-gallon tank. The maroon body with white lightning markings is truly eye-catching. After a few weeks, the colour deepened and the markings became more defined. I’ve had to be careful with tank mates, but it’s definitely a centerpiece fish that commands attention.

The fish arrived healthy and active. It has adapted well to the tank and shows strong territorial behaviour. I noticed the white striping became more vivid after two months. I recommend pairing it with a stable anemone species like Heteractis magnifica.

I was initially worried about the temperament, but the fish is more active than expected and very visually impressive. The lighting in the tank enhances the maroon and white contrast beautifully. It’s a great choice for experienced marine aquarists.
