I've posted about this before, sorry to keep repeating it, but just when I think my White's poop has stopped being runny it goes back to the way it was. I had him treated for excess protozoa but it didn't seem to make a difference at all. (Except maybe for making him extremely shy.)

I'm not sure what to do now, the antibiotics seemed to be hard on Bonk, but I'd like to eventually be able to introduce him to the big tank without fear of contaminating the tank/ the healthy frog. Am I going to have to keep him in a separate tank all his life? Should I go for another round of antibiotics? Or are the protozoa not that big of a concern?

Thanks.
