So my jardini seems to be suffering from something i have never seen before... seems like some scales are falling off a little and its seems to be breathing heavy. opening and closing its mouth alot. and lethargically swimming with its head near the surface. There seems to be a blood streak in its tail. so i think its bacterial or fungal infection. Just did a 50% water change in my 300. And its fins seems to have some redness. Currently treating Melafix and Pimafix. Anything else i can do?
