i took the water to the shop and the test was fine. however i will test it tomorrow too. because of the fish dying i got given two kisser fish. i didnt want them but he insisted so now im going to have to put them in the tank too - im not too sure how this happened i feel a bit confusedHello; I think this is the third thread you have started on the same tank problem. Seems very likely the fish are suffering from ammonia poison.
While the lfs may not have given you much in the way of proper advice, the truth is this is a very common thing in fishshops.
