Start by filling this out. Also with guppies what is your male to female ratio? No females as i didn't want any little guppies was also not advised I should have a female? I have only noticed his tail since I added the new guppies and the other guppy that was added at the same time is chasing the new addition around the tank but I've noticed it does tend to stand up to it and that 1 isn't showing any wear or tear to his tail. The other original guppy has a split in his tail fin which is also recent. I have live plants in my tank. I do have a picture but don't know how to upload on my phone! I have purchased some stress coat and some stuff for fin rot which starts with a m and has a funny spelling

(sorry I'm a newbie to this fish business)
