Hi - I'm wondering what people's experience is with keeping a mantis with fish? More specifically an N. Wenn. florida mantis. I've got a tomato clown - who I am not so worried about - and a lawnmower blenny - who I am more worried about - in a forty gallon. Both are about 3-4" long. The mantis who is currenltly in a nanocube is about 2". I would like to somehow combine the tanks because it's hard to maintain them both with my current work schedule
