Ok thanks. So I have another question one of the long finned black tetras is consitpated because his stomach looks bloated and he didn't eat today. I seprated him and tried to feed him a pea but he would just ignore the food floating right next to him and I even held it and ran it slowely across the surface of the water and he just wouldn't eat it. Would fasting work since I have no way to get around my moms crazy rule saying that I'm experimenting with the fish and she won't let me try anything like the pea, I had to try the pea when she was outside to do it. Or is he refusing food because of the fin rot?

Yes, I guess so. In Europe, the act of taking the peas from the shells is "shelling" the peas, so the result is peas that have been shelled, hence shelled peas. May be different in the US.
