Qt tank: just a bare tank, no rock, heater, if needed a pvc pipe to hide in. Can also include a filter (sponge or hob) with used filter material in it for an instant cycle.

Do you have any other fish in the system? If qt-ing and medicating is not an option you could always try adding garlic to their food every time they are fed for a period of time (hopefully someone on here would know how long is best). I have some garlic stuff at home for that purpose that you are welcome to borrow. I also have an "emergency" sponge you can have if you do end up running a qt and need that instant cycle.
