Poor Guppy :(

lol ive had angels and neons in my 20 gallon for a while also with a candy tetra, a hi fin black skirt tetra, a cory, and two otos, with about 2 tablespoons of salt everytime i change the water.

You might try putting your tetras in a smaller tank, a 2 or 5 gallon, if you still want to keep them.. As for your guppies, as long as they arent being picked at, their fins will grow back in a few weeks. If you like, you can add aquarium salt to speed the process, as long as you dont have snails or other invertebrates.
(If I repeated someone, I apologize.. I was too lazy to read the other replies! )

Anna theres no need to get on your high horse with me. I consider myself to be an experience fishkeeper, I've been doing it since I was 12. IMO salt (maybe not in a small quantity) will harm certain fish. A friend of mine recently lost several corys after salting his tank, so as many other fishkeepers, I will not use salt with corys. I certainly wouldn't keep them in a brackish tank as this is not a natural enviroment for them. I don't wish to be rude but this is just how I feel.

Anyway moving on to an update. I took the tetras back to my lfs store and got myself some *beautiful* new gups. One of the females is about the most colourful I've ever seen...and I got a gorgeous blue male.

The injured gupp seems to be doing great, he's swimming breeding and eating plenty (I put some tubifex worms in there today and he went nuts for them)...so panic over I suppose. I've got two huge females (they're about 2 inches) which are seriously gravid, so I'm hoping for a lot of fry soon...looks like it'll be time to get another tank (oh dear what a shame )

Oh, I'm sorry - you didn't give the impression of a very experienced fish keeper.

Besides, I was being somewhat tongue-in-cheek about the "rules" of fishkeeping varying greatly between fish keepers.

To quote a very experienced fish keeper, and owner of a very highly respected LFS in UK: "If the amount of salt is small it's neither here nor there to most species". It could be argued that keeping livebearers in 100% fresh water was as ill-advised as keeping corys and tetras in slightly brackish. If you want to house species from very different environments together in the same tank, a compromise must always be found. Which is why my personal view is that livebearers belong in a different tank to tetras and corys.

...urm...thanks

I can't see a need to keep any livebearers except mollies in brackish water. Having kept and bread livebearers for some years, IME it would be ill-advised to keep swordtails and platties in brackish water. Guppies however can adapt to it. This is irrelevant anyway, as most livebearers are captively bread and fully adapted to fresh water.
