I have read through your post on what to do and how to treat it and have done all that but to no avail.
They don't seem stressed at all and are all eating fine but i just cant get rid of it!
Any other advice would be much appreciated.
I have already lost one of my weather loaches who jumped out the tank and i didnt notice until it was sadly to late and i was beside myself to say the least

Oh i have treated them with Interpet Anti White spot which was recommended to me by Acorn pets, but im having no luck.
Thank You
