HI,we've alot in common. My blue Oranda has had these same conditions for years,I ve tried alot of different meds,ertho,then clout and resently pond fungus elininator. Unfortunetly for me, he or she is only worse and worse but I can't give up.He only lays on the bottom and moves his fins,and if he gets better like the last time I gave Ertho he can open his mouth bigger and eats again seems like he might recover but I think maybe I over feed him because I so glad he's able to.Relate? Well I'm going to him 1/4 water change tonight and try the ertho again tomorrow.I don't much about swimmbladders or anything but have alot bad experience.So I hope you will write back,and we compare notes.
