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?
