Yes very awesome. But i have researched them much because I was planning on getting a small one for my 12 gallon. From what I have read you should really build them a little cave, (in your case, a pretty big cave) because they love to stay in the dark and in a secured area until its prey has arived, then it runs out, brings it back to its cave and has its meal. But that is one awesome mantis and yes please put you hand in so we can really tell how big he is
How did you get him home? Wouldn't he be able to break teh plastic bag?
