I really haven't seem them munching on any plants. They could be eating some of the moss tho. I haven't really seem them eat much of anything. I suppose they mostly come out at night. This morning I was able to catch 3 sitting on the moss in different areas. They didn't scuttle away when I turned the lights on so maybe they are getting used to it. I would have got some pictures but I noticed a blue Malawa in my other tank and well I got distracted with taking bad pictures of them.
ROLL TIDE ROLL!!!
