Aquarium Advice Regular

Today I noticed my only guppy has a ragged tail right at the tip(he looked fine last night) ..He is in with 4 painted glass tetras... they get a long fine.
I had my water tested today and the p.h is high...Would this cause his tail to be like this?I have been looking through the old post before I ask..
I have a f/w 20gal with a penguin 125 filter and corner filter
underground filter and lots and lots of air bubbling going on...
Thanks for everyone's help
