Always thought they were pests, but I keep buying more. Wondered why I was loosing snails of late. So this morning I watched a cleaner poke at the snail until it retracted and fell from the rock.
The shrimp then proceeded to flip it over and started poking away at the snail, trying to eat it I assume. Of course up to my elbows in water just before going to work. Loads of fun.
Will be the last of their kind in my tank.
