That is a G. platysoma, 100% positive.
G. platy is the only mantis with that orange on black(blue?) tail marking. I have one, btw.
Some folks have remarked that they hide a lot, but mine is one of my most outgoing Mantis (I have 8 of them...). I have found that my platy (Glaurung) goes in for long molts (Several weeks at a time, once almost a month), but he is very active when he is not locked away.
Mibe prefers hermits to anything else, though he will eat thawed shrimp/scallop/squid, as well as snails.
Never whacks the tank wall, or the feeding stick,really.
An all around fabulous mantis to have.
Hope that helped a bit.
