If it is a gold fish, chances are it could be a water quality problem. they will usually turn red before they turn black if it is ammonia poisoning.
What are your water quality readings? Ammonia Nitrates?
Remember however, if you have a male and a female, prior to breeding, depending on the type of fish you have you will see tiny white spots and reddening of the gills.
If he is in a tank, and seems like he is having trouble breathing, do a water change. Also do not fill the tank up the entire way. Leave about 1/2 " and allow the filter to pour into the tank.
Also, is he showing any other symptoms?

Yes, likely ammonia poisoning. Do an immediate water change of at least 75%, and replace with temperature-matched, dechlorinated water. I'm going to guess you didn't cycle your filter before adding the fish, so you should be doing 50% water changes daily for several weeks until your filter is cycled. Get yourself a liquid test kit (not strips) and test your water every day. Any amount of ammonia or nitrite higher than 0 is deadly to fish. Good luck.

Could be from a number of things; gill flukes, bacterial infection, etc etc. What kind of fish? Are there any other fish that look sick in the tank?
What I'd do is research "gill disease" online (Google is great for this) and look for pictures/additional symptoms you might be able to compare it with. If you find out exactly what is wrong, you can usually treat it with medications from a pet store which will cost (usually) $5 - $10.

It is very likely ammonia poisoning. Since it is a goldfish, you should have at least a 10 gallon tank while its young, 20 if it is larger and older. I would recommend getting a test kit(liquid preferably) and start testing ammonia nitrite and nitrate every other day. Whenever ammonia or nitrite go above .25, do a 25-50 percent water change. Ideally you should end up with around 10 nitrate at the end of your cycle. If you need more info look up fish tank cycling

Fishes gills are normally dark, blood red. If they are another color it's a problem. If they are dark red, most likely all is well.
