I'm sorry about the rams, hurricanejedi 
You might want to wait for the spot to clear on that rummy before you re-stock.
One of my little male Pagwis started to develop columnaris in the saddle position. These guys were all infected on the mouth when I got them. I did a lot of massive water changes and it went away for a while. This guy has it back so I'm doing a round of Furan-2, nitrofurazone like the Jungle stuff, and hope this clears it out of the tank for good. If not, I'll try something else.
