Our Betta was being beat up by our current filter in a 10 gallon tank. We are going to get him a new filter that is adjustable this afternoon but I went ahead and unplugged the filter thinking it would cause less stress on him to just have his water still. He is spazzing out now though. He is fluffed and swimming around all crazy. Do you think he will be okay? Is it the change of water movement freaking him out or is it possible that turning the filter off released bad things into his water?
