My fe Mickey Mouse platy has been acting strange for about a week, she hangs out in the plants where before she was all over the tank. To my surprise tonight there was a fry in the tank. What!! She has been alone for 2 months or more. The only other fish are 2 oto cats. But now she wants to lie on the bottom. Just did a 25% water change at the beginning of her "weirdness". Temp is 70. Also she hasn't eaten that I can see. Is this just her delivery? or will I lose her?
