Sorry but this was not obvious to me... :-?
I just point out that, from the perspective of a recent newcomer to this forum and fish keeping, if I was to do what you both are suggesting each time i see something red hanging from the anus of a fish then most of my fish would be dead or i would have given up because of the cost and time treating the tanks. You may know that 'steve' has been around long enough but i have never seen anything he has posted before nor have any idea that his name is steve.
I am grateful for the help and info i have received on this forum and am aware of just how easy it is to panic when one is new to this game...
