Recently I have had two platies die with a week or two of each other. My first one seemed to become thinner but still feeding and doing what she normally did, I treated the tank with an internal bacteria med and a few days later another one dies, he didn't become thinner and seemed quite a happy boy but he died too.
I have one female platy left in a tank with 9 harlequins and 3 neons. She's keeping herself to herself hiding in one of my caves and only comes out to feed, is she on her way out too or is she lonely (I'm trying to get some friends for her shortly!)
I'm not sure if shes preg as she seems to be putting on a little weight but I can't find a gravid spot?? Should I re-treat the tank again or leave it for the time being??
The tank has normal stats.
Many thanks, I'd appreciate any advice?!
