Update: I separated 4 superhots sold together in a small container, here is the result:

It took me 3 hours to untangle them. I definitely lost some root mass along the way. I ended up putting the reaper, ghost and scorpion in a ~15 gallon pot and the habanero in the original ~3 gallon pot the peppers came in. Picture #4 is the before pic from yesterday. I also planted some sweet allysum flowers as companions. I used promix potting soil, miracle gro tomato at half strength, fish fertilizer and I scratched a little sprinkle of slow release granular fertilizer in for good measure. I sure hope they bounce back. Thank you everyone for your help yesterday. I will keep you posted on the experiment!
