I bought this clownfish for my 30-gallon reef tank. It adapted well and has been active since setup. The color is vibrant and it looks healthy. Just make sure to keep it away from smaller fish due to its aggressive nature.

It arrived quickly and the fish was in good condition. I’ve had it for two months and it’s still active. I noticed it defends its territory, so I added some hiding spots to reduce stress on others.

The fish is colorful and fits well in the tank. However, it does chase smaller fish occasionally. I’ve had to rearrange some decorations to give it space.
