The Passer King Angelfish is a stunning addition to my 100-gallon tank. It has a beautiful color shift from red-blue when young to blue-yellow as it matures. I’ve had it for six months and it’s active but not overly aggressive. Only a few small corals were damaged initially, so I added more space and monitoring. Highly recommended for intermediate reef keepers.

Great fish with striking appearance. I noticed it was slightly more active than other angelfish. It’s not a beginner-friendly species, but with proper tank size and setup, it thrives. The color change from juvenile to adult is impressive and worth the effort.

I bought this for my reef tank after researching hard-to-find angelfish. It’s beautiful and has adapted well to the environment. I keep a close eye on it to avoid any accidental damage to soft corals. The size range fits well in my tank setup.
