reeflobster vs mantis

[reeferious]

finally went ahead and bought a 4 in(body length) lobster from lfs last friday. b/4 dropping it into sump i heartily fed all 5 or 6 mantis first in case anyone of them had any unhealthy interest toward the lobster. got up couple times during the night to check on wellbeing of my newest addition who had already settled into its own plastic tunnel and was waving its white antennas about. i actually witnessed a wandered too near mantis being lashed across the head making a hasty retreat while a lumbering anemone hermit crab was ignored it's been almost 48 hrs now and this guy is still holding his ground chomping down on shrimp meat and silverside. does anyone has experience keeping reef lobster? life span? specie compatibility? growth size? it's such an interesting fellow i just might end up starting a lobster colony.
