White Clouds

Question
Hey Dave, my fish that looked like it was sleeping and every now and then got up normally sadly died this morning. I now only have 2 white clouds who are very pale, stay in the same spot in the tank all day [which is a corner up the top] and never go to the bottom why is that? they always have their backs touching the top of the water like just in it whats wrong. So, we get our water tested and where? a normal store? we live in Tasmania. can U find a place where they do that on the internet? thanks

Answer
Alisha:  did you get your water tested?  ;most aquarium stores like the place that you bought the fish from should be able to test your water... you are going to need to change about 40% of the water now... and maybe add oxygen... try the water change and see what happens... dave
