I’ve kept this fish for over a year in a 150-gallon tank. It’s active and colorful, though it does occasionally nip at smaller corals. The tank needs to be large and well-maintained. Overall, a great addition to a reef setup with proper care.

The fish is vibrant and active. I noticed it becomes more territorial as it matures. I had to remove a small anemone after a few weeks. Still, it’s a beautiful and interesting species for intermediate reef keepers.

It’s not the easiest fish to maintain. I had to monitor it closely to avoid aggression toward other tank inhabitants. The 150-gallon minimum is essential. It’s worth it if you’re prepared for the demands.
