My black guppy is sick I think. Is she dying? She has been like this for three days. She just floats around like this then swims a little, and she is lop sided when she does try to swim, she has tried to eat a little when I feed the other fish. Every time I think she is dead she swims some. She even comes to the top to try to eat but then seems to settle back to bottom for a while before she swims a little. Don't know what to do....
