then your only garuntee would be to observe the matis you bought's behavior.
mantis shrimp have unique individual personalities. i think the point people are trying to make is that you cant be garunteed that a mantis will be active just by the particular species.
some species do diff, stuff because of their specific characteristics.
but if you want an assured active mantis, you'd have to see it comfortable in a complete set up that it has been in for some time.
best chance, peacock.
cont do a peacock? Smithii or Wenne are great. but no way to tell how your specific mantis will act. maybe he had a traumatic childhood, or has low self esteem. you never know
