Saltwater Aquarium/Clownfish going gray


David, I have a pair of perculla clowns that I have had over a year and they have been doing fantastic. All of the sudden I have seen one of the clows very gray likes its loosing its color. It looks like a ghost of a clownfish. Not bright at all. I have no idea what is going on,heis still swimming around and eating fine. He doesn't look sick at all. I thought it could of been brooklynella at first but it doesn't look like it could be cause its his whole body and he's not heavy breathing and such. I haven't added any new fish but I have just treated with the chemiclean to remove cyno,and did the 20 percent water change. All my other fish are ok. What do you think this can be? I haven't changed the diet either. Thank you for your help

Hi Taylor:

No cause for alarm. Some Clownfish will change color as they age, when they pair off, and for breeding purposes.

As long as you don't see any fungus or parasites on your Clownfish, then more than likely it's changing its color naturally.

I possess over twenty-five years of hands-on experience and knowledge in the ecology of aquariums. Beyond the traditional, I have successfully tested and sustained environments that have been uncharted territories for hobbyists, for decades. I am the first to admit I don't know it all because there will always be something new, amazing, and exciting to learn about, as discoveries are made. It's a hobby one can never outgrow, or grow tired of.

After High School, my experience and love of marine animals influenced me to take up studies in Marine Biology. Throughout college, I studied Microbiology with an emphasis on Marine Life, as well as numerous other sciences. I continued to advance in this hobby, by building a dozen or more saltwater ecosystems all utilizing Microbes as the major source of my filtration method.
