Right place, right time.

I havent decided on a name just yet. He was making a chirping, kind of like a baby duck sound. He was completely buried in the substrate. I wasn't sure what it was at first until I saw the substrate move.

Do you have anything under the substrate other than the bare glass? If not it could be his feet rubbing on the bottom of the tank which makes a squeaky sound that has been mistaken for chirping.
