I have a Clown Cichlid who goes to the middle of the tank and kinda shimmies back and forth. I did all my tests and the only thing is my nitrate levels are a little high, is this the cause of the fish's eratic behavior? If so, how do I lower the nitrate level in my tank. I do a 10 to 15 percent water change on a weekly basis. Does anyone have any ideas for me? Please help, I dont want to loose this fish. All the other fish are fine jsut this one is acting strange. All ideas for helping me lower this nitrate level would be appreciated. Thanks
Doug
