Manits shrimp are best left to species only systems, the possibility of them being eaten or them eating other fish is a little bit too high. It also depends on the type of mantis shrimp as well
did we not already answer this question. if it is the kind of mantis shrimp that could be eaten it will probly put a hole in yur tank. Yur antennata will not eat a mantis. A full grown volitan MIGHT but there really is no fish that is know for eating mantis's.
