Recently one of my new guppies has developed what I believe is fin rot from another guppy nipping it. I think it may be developing onto ick as I see another fish with whiteish stuff on its skin as well as this one with the fin rot also has whiteish stuff on its skin. So I wanted to know if anyone knew of any medication I could use to try and cure them. It would be preferable that I can find it at a Petco or Petsmart. It also has to not harm any live plants or nerite snails because I have those in the fish tank as well. Thank you for your time!
