Why is my gold nugget pleco's color fading? Is it a sign of illness?

Pet's info: Fish | Unknown - Fish | Male | unneutered | 10 months and 24 days old | 0.3 lbs

Hi there, I'm not sure if this website applies to fish, but I don't have anyone in my area that can help. I have a gold nugget pleco and he eats veggies and driftwood all the time, has a large 55 gallon tank to himself and he has normal catfish habits-sleep during day, up at night. Anyways he was a beautiful black and gold but now his colour is fading... I looked it up and it means death (but he's eating and still very alive...). Is there anything you know about why else the colour could go?

Add some protein to his diet. This can be in the form of live, frozen or freeze dried blood worms or blackworms. You can also use your preferred search engine to look for "earthworm sticks" to feed him. Check the water quality as well (hardness, pH, etc.). Make adjustments as needed. Low water temps may cause stress and illness. Check your tank heater and temperature.
