A while now. However, when i bought the tank i just dumped in tap water and seven of the mentioned fish and they've all thrived. I even have some guppy fry (I removed them from the tank, since they're tasty little treats for all the other fish). The lady at the store told me all of my fish would die in a week (since I used a "new tank"). Fortunatly, as usual, I ignored what the people at the pet store told me. I've never seen such happy fish. (and the Jew in me was happy about the time and money saved).
