One of my sword-tails developed a swollen throat and a cloudy eye the other day, and so I put it in a quarantine tank and gave it a salt bath (even gently squeezed some down the thing's gullet in case its tongue was swollen). After a few short salt baths and a couple of days out of the tank its already looking better. However, I'm afraid to put it in with the other one just yet. If my little newt really is recovering, when could I return it to its home?
