The Regal Angelfish is a stunning addition to my 100-gallon reef tank. It has been thriving for over six months and its vibrant blue and yellow stripes are a highlight. I’ve noticed it’s slightly active but not aggressive toward other fish. The size is impressive, and it looks more natural than many other angelfish I’ve seen.

I bought this XL specimen for my expert reef setup. It’s beautiful and has adapted well to the tank conditions. The coloration is vivid and it moves gracefully. I do have to monitor its interactions with smaller fish, but overall it’s a great choice for a mature reef.

This angelfish has become the centerpiece of my tank. The vertical stripes are striking and it’s very active. I’ve maintained a 75-gallon tank with good water parameters, and it’s doing well. It’s definitely a showpiece that adds depth and character.
