Is this a Mantis Shrimp?

[AHHope]

by the colour id say a female chiragra
our larger looks very similar to the one pictured and we keep her in a 32g cube
as for tank mates she lives with a scooter bleny, a blue damsel, a chromis a LARGE emerald crab and a couple hermits as she went on a killing spree over the last 2 days
our smaller mantis is kept with a snowflake eel and a couple gobbies
they are the most clever inverts i have ever encountered and keepind them is a great pleasure
only once have i seen either of them fight with a crab and can hand feed the both of them
please keep her or find her a good home
