Just a note on color:
The color of marine life as observed in nature is not absolute and most times not completely natural.
The light diffusing capacity of a relatively shallow 30 feet of seawater can have a huge effect on how color is viewed and that gets more extreme as you descend.
Colors start to diffuse in order of the spectrum ROYGBIV. In 30 feet of seawater red is almost completely gone, yet only some of the true color can be represented by artificial light.
So, a basic orange clown fish on a Tahitian reef is not really the same color as the one in an aquarium. The only light an observer has is not going to be as full spectrum as natural sunlight at sea level or even in an aquarium.
So the true natural color can appear duller yet that is based upon a given depth and cannot be compared to what we perceive as the true color based upon what we see in aquariums?
