Hmmm...cories
The sand is around 3 cm deep with alot of cories, is it necessary for me to use a chop stick and go over the tank every water change
I am unsure of what you speak. Someone made a vague reference about a bubble, but I cannot think og anyone who has had such a problem. When you consider the years of fishkeeping experience on this forum with some of the more senior members, and none of them have had a problem, then you see just how minor a risk it is, if at all.andy...weren't you a part of the debate about this that went on a while back. I recall someone saying that a bubble rose from their sand as they were stirring it. A fish just happened to be right there and got smacked with the bubble or was very close to it I don't recall which. either way the fish started acting really wierd and died shortly thereafter. So I wouldn't go so far as to say don't worry about it it's nothing...more like don't worry about it just chase your fish away from where you are stirring and get a burrowing critter like mts snails to reduce the likelyhood and size of gas pockets forming.
