The Majestic Angelfish is a stunning addition to my 75-gallon reef tank. Its coloration is vibrant and it has become a centerpiece. I’ve had it for six months and it’s still showing strong growth in pattern. I keep it in a well-structured tank with plenty of hiding spots and it’s not aggressive toward other fish, though it does chase smaller ones occasionally.

Beautiful fish with bold patterns. It’s not the easiest to keep—needs a large tank and stable water conditions. I’ve had to monitor its behavior closely, but it’s a rewarding addition to my reef. The coloration is more vivid than expected at this size.

I bought this as a WYSIWYG and it’s exactly as described. The pattern is already impressive and it’s growing steadily. I’ve kept it with a few peaceful tangs and it hasn’t shown aggression. A true eye-catcher in any setup.
