PepperMan16... Welcome !
Are you growing indoors ? If you have them outdoors then just keep them far enough apart to let the sun hit all of the leaves. Life is good in that case ! Indoors under a grow light is a different story.
If you are growing indoors under a grow light, then the issue of spacing becomes an important consideration. When the plants mature, they can get very big and bushy. I have indoor plants that have canopies that are close to 2ft x 2ft. So two plants in a grow room would have to be 4ft. apart if you want to get the most out of the plants.
Since you have pots, you're already in a good spot. Just move them apart as they get bigger, or trim them as others have already said. You don't have to have huge plants to get peppers. If you look to have lots and lots of peppers, then you'll need to have a lot of space to let them grow.... and really good lighting.
Good Luck and Happy Growing !
