I came home and she was laying behind the cave with her head against the gravel. I noticed the water was a but cold, so I turned the heater up a little. When I did this she moved and sat in one of the leaved in one of my plants. The rest if the girls and the platy are all swimming happily so I know it's not the water. So I got my net and removed her from the tank and put her in a one gallon bowl I have. She ran away from the net just fine.
Her breathing seems labored, she has stress lines that come and go. She keeps sticking her head about halfway out the water, and then spitting up a huge bubble. She does this a few times and then she goes and rests on the bottom. Anybody have some suggestions of what's wrong with her/what to do?
