I just woke up this morning and I had turned my light off over night to my fresh water aquarium. It appeared as if my 10 fish were sleeping when I first turned it on. Now it looks as if all my fish are having a difficult time swimming up to the top of the tank and most sink and sit on the bottom.
Anyone know what the cause to this may be?
Many thanks.
