No clue whats going on!!!!
I have two balloon-bellied mollies in my ten gallon tank (one male and one female). Today, i found my female with her nose in the gravel floating straight up. She's barely moving and barely breathing. I tested the water and the parameters are fine. I turned the heat up a little b/c it was down to 73. Not the temp is around 78. The male is doing fine, i don't see any change in him. What in the world is going on?
