Why has my tropical fish changed Colour?

The fish are not sick; they are just changing color. Such changes may be caused by environmental factors (e.g., changes in water quality, sunlight, etc.), age or fish food. Enjoy your black goldfish. Keep them in bright light and they will develop a nice rich velvety black color.

What does it mean if your fish is losing color?

If the water quality declines, your fish are likely to become stressed and may even become more susceptible to disease. Aquarium fish that are stressed or ill are unlikely to display their optimal coloration and they may even fade in color as a result of stress.
