I bought this fish for my 80-gallon reef tank. It’s aggressive and has chased a few smaller fish, so I’ve had to rearrange the tank layout. It’s active and interesting to watch, but not suitable for a community tank. I’m okay with it as long as I keep larger fish and avoid small invertebrates.

The fish arrived healthy and seems to be adjusting well. I’ve noticed it’s quite territorial and doesn’t tolerate other fish well. I’ve placed it in a corner with plenty of hiding spots. It’s not for beginners, but it’s a striking addition to a larger tank.

After a few weeks, it’s established and very active. I’ve kept it with a few large, hardy fish and no corals have been damaged. It’s a bold choice, but it adds a lot of energy to the tank. I would recommend it only for experienced reef keepers.
