A few weeks back my female motoro got sick and didn't make it through the treatment. I treated the tank with melafix for one week, then pima fix for one week, and everything seemed fine. I now have one ray that is bloated, and less active, but still eating and a tigrinus cat that is now acting oddly and seems sick. I am at day 3 or a second melafix regiment, as it seems bacterial infectin was the culprit lst time, and am in the process of a 30% change to ensure proper water quality/paramers. I would also like to raise the temp into the mid to high 80's if possible. My question is, will the rays be ok somewhere around 86? I keep reading mixed opinions online, so, if some of the more experienced keeper could steer me in the right direction, that would be great. thanks
