I totally agree with you Jason, bloat is always triggered by some form of stress. I was just thinking that with new fish, especially those that can be prone to bloat, a little preventative maintenance never hurt. So if those new fish arrive carrying S. vortens in their gut, knocking the numbers back to near zero could give one that extra buffer against a bloat outbreak while the fish are acclimatizing to their new surroundings, and possibly a new diet. Just a little added insurance, without utilizing harsher medication.
