Well just noticed lastnite in my newly set up BC29. A mantis shrimp about one inch scurrying around on the rock (by the way is teeming with life) Can't be more pleased with how it looks, so diverse. Since this system is such a small one I most likely won't put in any fish. Except the Blenny that came in with it. Possibly a maroon clown I have in holding tank. Ricard put a flower pot and condy in with shipment(thanks) I was wondering if the shrimp should be caught now or should I not worry about him?
