These 4 Mollies are the only fish in the tank. The are 3 small fake plants in the tank & a treasure chest decoration. Do you think it is overstocked? These guys are smaller, nothing fancy. They are not even 2" each. Is it because this is a smaller tank? LFS told me I could add another Molly or 2 or a couple of guppies but I haven't because I didn't want it overstocked. Could this be part of the problem?
Also, was wondering what medications people have had good luck with when treating Columnaris?
Thanks again.
