I have a pair of 6-7 month old fh's that are breeding, eggs have been laid and removed, not worried about all that. What concerns me is that the morning after egg laying I noticed white poo in the tank. Have always done, and still do 30% water changes weekly along with maintenance of the biowheel 350 and magnum 250 (55 gal aq, btw, yeah yeah too small, I know). Have never had any white poo in the past, any correlation with the breeding? Really don't want to use any chemicals, so far have only salted the tank, any suggestions?
