I have a 10 or so inch in my large tank and he is determined to take all the sand under the rocks and move to above the rocks. He never stops digging and tunnelling. I'm beginning to worry that the rocks might fall. I would like to catch him somehoe safely and place him in my 90 gallon, but don't know how. I would have to totally empty my larger tank to get him and would rather not. I was thinking of some type of pvc pipe trap. Any help or suggestions would be appreciated. Thanks Eddie
