Big and Evil
I have a 150 with about 120 pounds of live rock in it that I have taken to looking at with a flashlight at night and have seen many small shrimp all over the tank that I did not put there. most look like mysis shrimp is this possible? however, on one occasion I did see something that looked alot like a mantis I think it was so small it was really hard to tell. Nothing has dissappeared yet so I am not that worried, but I would rather not wait till things start to go bad to do something about it. What are some good ways to lure them out where they can be seen? the one I saw was like maybe 1/2 inch.
