If you are doing everything right they do it simply because they can. The basic rules are :- 1 inch of fish needs at least 1 gallon of water (an active Guppy needs at least 3 gallons but 10 gallons is better for a couple). :- Every tank needs a permanently running cycled filter. :- Every tank needs at least 50% of its water replaced every week.. A Guppy likes a pH of around 7 to 7.2 and a temperature of around 70F to 75F. They should be fed as much as they can eat in 15 minutes every morning and evening.

Sorry to say, But he is dying. The nipped fins might be because he was attacked by another fish. And since that happened he probably can't swim as well.
