I recently purchased this underwater sand fountain for aquariums. It plugs into the air pump and feeds a constant rotatin of aquarium sand, pretty cool. The fish seem to be eating the sand? they poop red (the colour of the sand). So far this seems to cause no problems but I wonder, if they get constipated, how on earth do I stick a suppository in its you know what????????
