Depends on the mantis species. Some of the smaller species would be ok in a 10g tank. Is it a wet dry or a refugium? You would need to take the necessary precautions to avoid the death of the mantis from your equipment. Ie. be sure that the mantis can not get stuck in your return pump etc. You would be lucky indeed to find a mantis in some of your LR (although some would feel quite differently about it).
