By definition, I would say it means going through a metamorphis, (or in this case) a color change. Basically it's when young juveniles turn from thier grey color to their brighter mature color. This could be, Peach, orange, red, white, tri color and anything in between.

The color of the fish is decided by the color tissues (chromatophores) on skin layer and under its scale. There are some basic kinds of color tissues consisting of black/grey (that people call normal morph), red, orange, yellow, blue and white ( that people call color morph). Color tissues contain pigment that it reflects with a specific light wave. For example, red tissues reflect red light and absorb all other color waves then fish look red.

Now, back to your question about color changing of a fish. It happens when a normal morph is unable to create black pigment (melanin) then fish becomes any of color morph. White color is a special case when fish is unable to create any pigment (albino). Color morph is found in fish fauna living in deepwater in both sea and freshwater. Normally, color morph has less chance to survive then normal morph because it is easier to find out by the predators as larger fish, reptiles, birds...but in deepwater where almost no light, both morphs are all look the same dark! Color morph is one of evolution strategies of fish in deepwater becasue they spend less energy to create color pigment than black pigment.

In case of RD/Midas color morph, although they live deeper then normal morph but still in places where red light can reach. People says because of that color morph will be extinct in future. Others say that explains why the color changing in RD/Midas happens late, sometimes up to 1-2 years until fish is big enough to overcome any enemy threats. However, they are all theories, in fact, both morphs are existing in natural environment of Nicaragua.

Hope this will help.
