Ruth Fraser –
I kept this fish in a 75-gallon tank with some rockwork and it has been active. It’s aggressive and not suitable for small fish, but it adds movement and presence. I had to remove a small shrimp after a few weeks. Overall, it works in a well-established tank with proper spacing.
Paul Hudson –
The fish arrived healthy and was active from day one. I noticed it was territorial and chased a small snail. I now keep it with larger, robust fish. Not for beginners, but it can be managed with a large tank.

After a month, it’s grown to about 4 inches and shows strong activity. I’ve maintained a good water condition and avoided adding small species. It’s a bold addition to a reef setup with proper planning.
