prazi, isnt that the one we cant get over here? im sure i looked into and its illegal over here. i QT new fish and i add salt if i see any white spot, ive not had to treat for anything more...yet. i didnt QT the 2 new guys as my friend had had them in a tank by themselves for over 6months, infact it could have been longer, i forgot when she got them. all the other fish are fine, no floaty issues. bossfish was the only addition from this particular shop and i decided not to go there again as i found out he would have them up for sale from the day they were delivered.
