Do you have any largeish pebbles? These fish like to build - they will redesign the tank to their own specifications. Mine has dug a big hole in the gravel, then lined it with pebbles, and then moved one of the plants next to the hole - he's happy for the moment, but will no doubt soon start redesigning - it's comedy to watch.
