sick guppys...Help

[Anonymous]

Hi, I'm looking for some help with my guppys, I had 5 that I got from a friend to start my clan of babys 3 females and 2 males. I desided to get a few more to breed with them I took one of the five and put her in a new tank both tanks are over a month being set up now. So I go to the pet store and found four that I liked in collor and finage, I put 3 in with the female 1 male and 2 females and the other female in the other tank, I have lost all in the new tank I set up with the female to get it started good and now my other tank is showing signs of the same. they start out swimming at the top of the tank with tight fins and then white stuff that looks like cotton (it's not ick) and one of the males looks like hes tail is rotting off. I tryed a stuff called fungus clear tabs from Jungle that is supossed to stop two of the things that is wrong fin rott and clamped fins but is rapidly getting worse and I don't want to lose my babys can anyone help...?

Hi
could you give me more information about the water conditions.

Also you could add some salt to the aquarium since salt prevents many infections etc.
