I got a female guppy about a week ago. Tis morning I noticed she has a red mark on her side. Almost like red bruising on humans. She's also been swimming right at the surface for about 3 days now. Any ideas?

Possibly high ammonia levels. Fish will sit at the surface and their skin can go red with ammonia burn if your ammonia is too high. Does she appear to be panting/gills flapping?
