This Emperor Angelfish is a breathtaking addition to my 100-gallon reef tank. The coloration is vibrant and changes beautifully as it settles in. I’ve had it for three months and it’s become the centerpiece of the display. It’s semi-aggressive but not overly so, and I’ve managed to keep it safe with proper tank layout and hiding spots.

The fish arrived healthy and showed strong coloration right away. It’s grown to about 6.5 inches now and looks more like a full adult than when I first got it. I’m cautious about its interactions with smaller corals, but overall it’s a stunning and impressive species.
