 They often have their back end under the rocks and extend their head? out into the open sand areas to feed and poop it out the back, under or around the rock.  My rock is mostly at the back of the tank so it tended to accumilate there.  With my inch and a half sand bed, It took about 2 years before i could start to see the glass on the bottom at the front
