The clownfish arrived healthy and vibrant. It’s quite active and shows strong coloration. I’ve kept it in a 30-gallon tank with corals, and it hasn’t damaged any of them despite being aggressive. Good for beginners who want a bold, colorful addition.
Austin Murray –
It’s a striking fish with a clear white stripe. I noticed it’s more active than other clownfish species. I made sure to keep it in a spacious tank with plenty of hiding spots. It’s not the most peaceful fish, but it’s visually impressive.

The fish looks beautiful and matches the description. However, it has been a bit aggressive toward smaller invertebrates. I plan to monitor its behavior and adjust tank layout accordingly.
