Can excevating fish cause mini cycles?

[jbird69]

I have always heard you shouldnt disturb your sand bed too deeply. Some people like to stir the top 1/2" but avoid going deeper as not to disrupt the benefits of a sand bed.

My clown fish has taken up a bad habit of excevating by fanning his tail. He does it right where his anemone touches the sand. The sand bed varies in depth in my tank but it used to be about 4" below the anemone. My clown has dug a pit thats nearly to the bare glass and probably 6x12".
Should I be worried about the disruption of the sand?

You would have seen any problems by now I would think.

In a smaller tank if it was dug all at once I think you might get a noticable problem, but as it was dug over the course of a little while I would be surprised if you had a measurable cycle in a mature tank.

My anemone moved closer to the sand last night and now my clown is doing the exact same thing. My Goby already keeps my sand pretty sifted though.
