Blue is a colour, the perception of which is evoked by light having a spectrum dominated by energy with a wavelength of roughly 440–490 nm. It is considered one of the additive primary colours.

Cyan from , transliterated: kýanos, meaning "dark blue substance") may be used as the name of any of a number of colors in the blue/green range of the spectrum. In reference to the visible spectrum cyan is used to refer to the color obtained by mixing equal amounts of green and blue light or the...

Yellow is the color evoked by light that stimulates both the L and M cone cells of the retina about equally, with no significant stimulation of the S cone cells. Light with a wavelength of 570–590 nm is yellow, as is light with a suitable mixture of red and green...

. The colors of the juvenile fish help them to blend in with the reefs. The queen angelfish may live up to 15 years in the wild and reach up to 45 centimetres in length. Queen angelfish are about three and a half pounds.

Diet

The queen angelfish feeds primarily on sponges, but also feeds on tunicates, jellyfish, and corals as well as plankton and algae. Juveniles serve as "cleaners" and feed on the parasites of larger fish at cleaning stations. Although in home aquariums, aquarists have been successful in providing the queen angelfish a diet of meaty and algae based foods

Reproduction

The adults are found in pairs year round, perhaps suggesting a long-term monogamous bond. The pairs reproduce by rising up in the water, bringing their bellies close together, and release clouds of sperm and eggs. The female can release anywhere from 25 to 75 thousand eggs each evening and as many as ten million eggs during each spawning cycle. The eggs are transparent, buoyant, and pelagic, floating in the water column. They hatch after 15 to 20 hours into larvae that lack effective eyes, fins, or even a gut. The large yolk sac is absorbed after 48 hours, during which time the larvae develop normal characteristics of free swimming fish. Larvae are found in the water column and feed on plankton. The larvae grow rapidly and about 3–4 weeks after hatching the 15–20 mm (0.590551181102362–0.78740157480315 ) long juvenile settles on the bottom.

In aquaria

Although, the queen angelfish is considered to be moderate in difficulty to keep in captivity, it is ill-suited for the inexperienced aquarist. They are an aggressive species that require a large aquarium. Most aquarists recommend a minimum tank size anywhere from 150 on up to 180 gallons. The queen angelfish will harass other fish without discrimination, particularly new additions to the aquarium. It should be the last fish added to any system. It is not a reef safe fish, and larger specimens may nip at or consume corals, particularly stony or soft ones, and ornamental invertebrates.
