Hello, I bought a 10 gallon tank the water levels are right ph and everything. I just recently bought two Dalmatian mollies a male and female. Yesterday the female was chasing the male around I was worried but read it was to show dominance or she didn't want him breeding her. They stopped today when I went to work so I ignored it. When I came home I checked on them and noticed that the male was laying sideways on the bottom of the tank. Thinking he was dead I went to net him out and he swam away. I was watching and noticed that his left fin don't seem to be working, and my ghost shrimp push him upright when he falls down. I don't know what to do to place him into another tank or leave him in the tank or what might have happen or if he will die or be okay. any help is much appreciated. I'm highly worried about him. thanks
