My guppy is swimming at the bottom of the tank and has been doing so for the past three days. I'm not sure what's wrong. Is he depressed? There are two other guppies, a baby and a large female. There are also two tetras and an albino cory. He doesn't appear to be swimming sideways or brushing himself against the gravel. He just swims around at the bottom and rests periodically.
Help?
