Some colour variations in the Queen Angelfish (Holacanthus ciliaris) are shown in this paper. These morphs belong to an isolated population resident at Saint Paul’s Rocks, a group of small islands in the tropical central Atlantic. Some factors like homozygous following inbreeding and low genetic flow are considered the probably causes of this phenomenon.
