Bugs!!!!!

Well, it's a good sign here in Oregon to start seeing moths etc.. It's a sign of warm weather to come(and fishing and floating the river and camping and boating and Oregon stuff). Except I have an open top. I'll be netting bugs from my tank alot in the future. It's kinda funny to watch my fish try to attack/eat moths fluttering on the glass. I wonder if the moths have anything toxic to add to my tank. It's never caused anything more than a burden to me yet.
