Hi, I set up my first tank 2 weeks ago. Followed the instruction book that came with it. I washed the gravel & decorations before adding then filled with water, I added aqua plus water conditioner and nutrafin cycle. I was told that I should leave the filter running do partial water changes every 3rd day and that I could add fish after 7 days. So last Saturday we went to the pet shop had the water tested, it was fine and brought some guppies 8 female and 3 males. By Tuesday night they had all died. Had the water tested again on Wednesday and was told the water is fine. So why did they die? Also they left behind 10 guppy fry which are now about 15mm long and seem to be doing really well. So what should I do now because I want to end up with a tank that has 3 or 4 types of fish in it.
