Queen Angelfish (holicanthus caliaris) reign over the tropical western Atlantic waters from the Bahamas to Brazil, sporting their vibrant blue-ringed crown. Like royalty, they keep to themselves, occasionally giving a nod and a wave to a passing diver. It appears (despite tabloid rumors) they pair up for life. In general, Queen Angelfish are polite and amiable. However, there is no love lost among adult males who can be aggressive toward each other. While waiting in line for the throne, the entrepreneurial juveniles set up stations among the reef where they work cleaning the parasites off of other fish. $1.00 50 cents, 25 cents per parasite. Times are tough all over.
