Is this Heterometrus longimanus?

Yea there's some differences between female and male granulation, but that's a Heterometrus silenus.

Ah ok, which one is the female? heavy granulation (your pics)? or light granulation (my pic)?

Yours looks female based on the operculum, mine is a male.

Here is a pic of my 5i H.silenus (suspected male). It seems to be similar in development to yours.

Can you zoom in on the cheek granulation, chela, and operculum for comparison?

I just got another one.
This new one has the most chill temperment ever, literally ZERO defensiveness/aggression, it even lets me pet it with a paintbrush (figured this out when trying to get it to move into its new enclosure).
Whereas the first one is a little ball of hate and gets mad if i so much as look at it from 2 feet away.

Interestingly, the angry one seems enthralled with the new one, and as soon as it saw the new one it stopped being aggressive.
I'm hoping they are opposite sexes so I can breed them, but i haven't had the chance to check its underside just yet.
