Jack Dempsey moving sand

[Oscar_Mania]

Ok, I have a sand substrate in my tank and I have a number of flower pots in there as well. Over the last couple of days my Jack Dempsey has moved all the gravel out of the larger of the flower pots and placed it all in a pile outside of the pot. I'm just curious about this behaviour because he's the only JD in the tank. Could he just be bored?

thats just the way they are. my jack is always moving gravel around. Sometimes she even digs down to the glass.
