Extra Tanks? Please help.

Hey Everyone

Lately, in the past month, I have lost 3 fish, first an anthias, second a yellow tang, and 3rd the other anthias, to some diseas that seems to appear and kill perfectly healthy animals within 24 hours. I have set-up a 29g QT tank which I will be moving our two favorite fish into for now and there will still be 5 fish in the tank. If another one dies, I would like to isolate all the fish until I can re-do the rock, sand, and water. I do not have any tanks to do this with, and I am asking in advance, incase I do lose another fish, if I could please borrow for a month or so any tanks from 10-30g.

Thank-you very much!

Chris
