Bought this for a 100-gallon reef tank. It’s active and shows good coloration. I had to remove a few small fish to avoid aggression. Works well in a larger setup with strong tank mates.

The fish arrived healthy and seems to adapt well. I noticed it’s quite dominant and has chased a few smaller fish. I now keep it with larger, more robust species only.

Great addition to a mature reef tank. It’s not shy and adds visual interest. Just make sure the tank is large enough and has no small fish or corals that might be at risk.
