Joe Hill –
I added this fish to my 80-gallon tank after researching compatibility. It’s aggressive and needs a strong setup with plenty of hiding spots. I’ve had to monitor its interactions with other fish closely. Still, it adds visual interest and is active during the day.
Christian MacDonald –
The fish arrived healthy and seems to be adjusting well. I’m cautious about keeping it with smaller or delicate species. It’s not for beginners, but it’s a striking addition to a well-established reef tank.

After a few weeks, the fish has become more active and shows interest in the rockwork. I’ve kept it with only hard corals and it hasn’t caused any damage yet. It’s definitely not a low-maintenance species, but it’s worth the effort for experienced aquarists.
