I bought this clownfish for my 30-gallon reef tank. It’s active and colorful, with a distinct white stripe. It’s been a few months now and it’s still healthy. I did have to keep it separate from smaller fish due to its aggressive nature. Overall, a striking addition to the tank.

The fish arrived quickly and looks exactly as described. It’s vibrant and active. I’m a beginner and found it easy to care for. Just make sure to keep it in a tank with enough space and avoid housing it with small fish.

It’s a nice-looking fish, but I noticed it’s quite aggressive. I had to move it to a corner of the tank to prevent it from chasing other fish. Still, it adds a lot of visual interest.
