so i have had two banjos now for about a month now, the only time i ever see them is when i dig them out of the sand to make sure there still kicking. my question is do they eat algae. i have a bad algae problem right now and one of the banjos is out and about going all over this algae, ans his stomach is full. i am amazed to see it even moving. or is he just that comfortable in the tank that he has decided to come out.
