Thanks, Wright! Do you by chance know anything of the symptoms which
Gyrodactylus should cause, which I read are 'spiderweb lesions in the skin
and reddened fins' another article talks about ' gray-white patches on the
skin and bloody spots'. Nothing of that, a bit strange I think.
I'm currently using a 'miracle cure' (eSHa2000) which also is against
Gyrodactylus and gill flukes. Strangely enough only the praecox are infected,
all other fish seem fine, even the guppies. Just took another very close look
and it's on their eyes too, maybe this is important for the diagnosis?
