Has anybody ever tried these together. My one is really docile and does not kill or harm any animal it comes in counter with. I was thinking of trying my new one in the same 25 gallon tank

NOT A GOOD IDEA! P. ciliata are highly territorial and will fight vigorously. WIthout a smashing raptorial appendage, their spears are not necessarily lethal, but if one molts, it will probably be killed.
Even sex is rough in this species. Males are coy and females will actually chase down males and harrass them unltil they copulate. I've seen one female go through four males in an hour.
Large P. ciliata actually hunt smaller Gonodactylids.
Here is an abstract on P. ciliata mating. Sorry, but I could not download the PDF.

Abstract
The first known case of precopulatory role reversal in a crustacean is reported here in the stomatopod Pseudosquilla ciliata. Females of this species initiate courtship through visual displays and a vigorous sexual chase. Males enter courtship with restraint and appear to exercise choice by copulating selectively with females larger than themselves. This singular reversal in courtship roles occurs in the absence of paternal care, female guarding, or other male investment strategies typically invoked to explain such behaviour. Males, however, face certain risks in breeding, including the threat of aggression from the female, and the loss of a considerable part of their reproductive investment through sperm competition. By mating with larger, more fecund females, males reduce the potential loss from sperm competition, but increase the risk of injury from the female. This combination of factors should promote caution in males along with a preference for larger females.
