How do you know when a Stingray is Tagged?

[Jesseliu13]

I have a pair of Marbled motoros... I am still new at the breeding process, but the male is rolled claspers (and gaining weight correctly. FINALLY) and my female should be ready as she is pushing 16-18" Diameter. how can i tell if my female is "tagged"?

Can be pretty tricky unless you happen to see the sperm plug in the female

i have yet to see it.. but my male keeps trying to flip her, female not having it lol.

If he's trying I'm sure he'll get there in the end
