I've had 8 guppies for about 3 weeks now. I noticed one of them started spending a lot of time by himself a few days ago. Now all he does is swim in the same spot near the surface by himself. He doesn't even really use his big tail anymore, just the two small fins to swim in the same spot. Sometimes he'll dart around the water almost jumping out, but he mostly stays near the surface by himself with his tail drooping. Today I noticed another guppy starting to behave similarly. Are they dying? I checked my water parameters and they're all good. I don't see anything wrong with the guppy physically and my other fish seem happy.
