Update: I lost the new introduced catfish sometime thru the night . luckily he was moved to a 40 breeder to he didnt spike the ammonia level in my 220.
All of my catfish were moved back to the 220. I did a 70% WC again last night, kicked temps up and added medication. What ever signs of disease they had are going away, there appetite is back in full swing, I am very happy with the results.
LESSON LEARNED: Qaurentine your fish, big or small. DO NOT be lazy.
I'm still baffled as to what the problem was but im more than happy to see it go

Never thought i'd have to pull a dead catfish out of a tank.. was really depressing
