I have a similar problem with my 10 gallon guppy tank. Something fast, came through and killed every adult guppy one by one in about a week but it didn't kill the baby guppies for some reason. I tried to look up a video if baby guppies can still survive if you have columnaris? Without any success. Anyway, whatever it was brutal. It picked out 2 or 3 per day. They all went to the top staying near the air bubble's, then after exhaustion they went to the bottom where they later died. I didn't see any saddle back color on my fish except two female guppies that had a little bit of gray 🩶 patches near the dorsal fin. None of the other's had white spots or discoloration. It started with one red tailed female. I grabbed her out with the net fast hoping she hadn't spread a disease. Two days later, two more. It COULD have been columnaris but I don't have anyway to test for that. Wish I could have helped you. Good luck 🤞 I have a similar problem with my 10 gallon guppy tank.
