OK got the puffer in the QT and a refractometer.
Good start I guess.
I'm putting the temp in the QT to about 82 and will start making the water changes with fresh water tonight since there was already a .03 drop from the DT to the QT.
I know everywhere says to take all fish out of the tank for 8 weeks, I went and talked to the dude at the LFS
and he said to just do the hypo with the puffer leave the others that aren't showing signs. I know this goes against everything I've read but is there a chance I could treat only the puffer until no more ich and have a chance by putting him back in without treating the others?
Or of course cramming all 4 fish into the 30 gallon, I'm not sure which is the better of the two?
At least now I can breathe cause I know the puffer is safe..
