I’ve had this clown tang for six months in a 120-gallon tank. It’s active and colorful, but it does chase smaller fish. I’ve had to remove a few small species to keep it calm. Water parameters are stable, and it’s grown to about 5.5 inches. Worth the effort for experienced reef keepers.

The fish arrived healthy and looks vibrant. It’s been in my 100-gallon tank for three months. I’ve had to monitor its behavior closely, especially during feeding. It’s not aggressive with larger fish, but it does nip at smaller ones. Good for a well-maintained tank.

I expected more color and activity, but the fish is quite shy at first. After a few weeks, it started swimming more. I noticed it’s aggressive toward smaller invertebrates. I’ve since removed a few snails. Still, it’s a decent addition to a large reef tank.
