Biggest Peacock Mantis I have seen

yup like dun said, the unfortunate answer is an absolute no. Most mantids will just pick eachother off until one or none are left. It is possible for a few to coexist for a few species to coexist given the proper conditons but most mantis owners don't bother with the risk.

mating is another issue. a few species will form monogamous pairs but most will mate then leave. in a tnak they obvisouly can't get away anywhere so the smaller mantis will usually die. not fun. besides, raising mantis larvae is MUCH more difficult than raising most fish larvae.
