The Blue Ring Angelfish, also known as the Ringed Angelfish or Blue King Angelfish, is a strikingly beautiful tropic fish and the feature of this photographic personal check series. Stunning underwater photography shows this unique coastal reef inhabitant that actually changes colors and patterns as it matures. The neon blue stripes remain, but the body color can mature from dark blues and blacks to more vibrant shades of yellow/orange/brown. The vibrant blue stripes make it a popular choice for aquariums.
