How to tell a solid lock?

Any idea how to tell if theres a solid lock or not? I've been putting my male and female together for 3 days on 3 days off for almost a month now and I haven't seen anything close to them "getting along" until yesterday and today, yesterday they were laying on top of one another and today i saw what might have a been a lock... below is a picture of what I have going on now... any advice is appreciated.

that senor! is a lock!

its funny but dont be looking for thrusting and deep panting :-)

they arent like us.

but also, it could be as quick as 10-15min. to as long as 10-15hrs.

so dont be surprised if its a while between locks...


my male pastels a minute man! he's been locking up with my norm-F for a month or so, but never longer than about an hr.

just keep pairing and you wont be let down!
