From what I've gathered in the short period of mantis ranchin' here in the great southwest, when you have a large tank, 10 gallons is small for a texans big haid, but large for a small mantis, then even the large mantis' may have difficulty finding it's food, since they usually lay in wait and ambush prey. Some varieties will chase down food, but a large tank may get a hungry mantis in an awful way
The suggestion of ghost mantis' is because they are one of the varieties of mantis that are communal, and don't lean as much toward canabalism as other mantis' do. So if'n you use ya a 10 gallon tank, you may want to fill it with a communal variety of mantis, and keep in mind that some may go hungy, and start canabalizing the other 'fatter' ones, that may appear as donuts do to homer simpson.
Studies have been done with other types of predators, and those that are fed a decent protein diet are less likely to canabalize their brethren, unless they're politically inclined mantis', of course.
If you're going to house them communally, all together, then feed them well, and give them space to hide and perch for food, and plenty of food.
You can house communally a variety that is canabalistic and watch the show. The survival of the fitest and natural selection will take it's course, and you will see how the earth has evolved to what it is today, a mass of greedy, self-centered, inconsiderate idiots. Oh, did I say that out loud...
Hmmm, I'm gonna have to get that looked at and get back to you..... ........ .........
