Hey Zack, I have personally witnessed one of your mantis go after a fish. I admit that his attack was unsuccessful, but it wasn't for lack of trying. I wouldn't advise keeping them with fish.
.com rock is the finest product available simply because it is "live". I wouldn't trade "mantis free" for the loss of any other organism on that rock.
My mantis was easily captured, with preservation of all life on the rock as the main priority. He (she) now lives happily in his (her) own tank. In fact, I would be down right disappointed if I hadn't got at least one mantis in my shipment!
