The fish is very colorful and adds a lot of visual interest to the tank. I noticed it became more aggressive after a few weeks, so I made sure to keep it alone and avoid adding new fish. It’s a great centerpiece if you’re willing to manage its behavior.

It looks stunning with its black and white stripes. I expected it to be more peaceful, but it started chasing other small fish. I now keep it in a larger tank with only compatible species.

A striking addition to my marine setup. The black tail is very noticeable. I’ve had it for six months and it’s still active and vibrant. Just be cautious about tank mates.
