This guy is pretty young, maybe a 1 year plus a month or 2 but I've noticed some curiosity happening with my female.. a lot of rough playing.. I'm in the middle of remodeling my bathroom and haven't had the time to watch and enjoy my tank like usual. But I've noticed my females disc is a bit beaten up around the edges..also on another note I was wondering what the salt ratio would be to help her heal and keep infections away?
