Water was treated, water was heated to same temp (using spare heater) before adding.BerryAttack said:you use tap water?
if so then you didn't treat it... if you did treat it then what are the stats of the water.
how much water did you change?
if the temperature of the water was very different from the tank, and if you change a very large amount then the temperature difference could have shocked them... stressed and killed.
how long was the tank set up?
details man we need details xD
