Ok. At night my wife told me she heard a cicada noise coming from the tank. I thought she was crazy. She later showed me the noise and I did hear it. It sounds like a smaller/softer cicada noise. There is no way I have a hitchhiker as I used dead rock. No live rock was introduced. I have one clown, snails and 2 hermit crabs. Could any of these guys be making this noise?
