it accuers when a fish of a higher rank dies and if its a different sex it will change parrot and clown fish do this
The refraction of rays of light as they leave the water will cause the fish to appear in a different position i.e further away and closer to the surface. In order to spear the fish the fisherman will have to aim slightly in front of the apparent position of the fish.

I guess you are asking about "Algae eating fish" If so, then there are so many different species of fish that eat algae that it is impossible to advise you on their colouring. You will need to be more specific.
It depends on what type of fish change colors, like for example a black moor fish can change color by its temperature.
