This butterflyfish is stunning in appearance. After months of research, I finally got it and it’s become a highlight in my marine tank. I feed it copepods daily and it’s active and healthy. Only recommend for experienced keepers with proper feeding and water conditions.

Beautiful fish with unique coloring. It’s not easy to keep, and I had to adjust my feeding schedule and water parameters. Still, it’s worth the effort for the visual appeal.
