Congrats! Now, they're starting to look a little leggy, so be sure they get plenty of light. And don't over-water lol.

Very nice! I agree with them being leggy. When you separate or cull and repot bury the stem deeper into the soil. I agree with supplemental lighting if you can provided some it will keep them from getting leggy. Also if this was from a store bought pepper it may or may not grow true so you may have a cross on your hands. Either way it should be a good pepper. Keep us updated on the progress.
