There are very very tiny white worm like creatures varying from .5 to 1mm in length and less than .01mm across (I cannot tell if the body structure is cylindrical or flat) and only slightly opaque so visibility of them through pictures is almost impossible. They seem to be very slow moving and are able to leave the panes of glass and become free-floating. Some are large enough to be seen wriggling in the water itself. Even though they do not seem to be effecting the fish I thought it was appropriate to post in this forum because one can never be to certain or to careful.
Any ideas what they are and could someone suggest a good treatment?
