well... its prolly not a true hystrix stingray because they are illegal to export from brazil which is the only place they are native to. sooo.... its prolly going to be a humerosa style ray which get the same size as motoros around 24" disk. but to answer ur question.... it all depends on the size of it.. and the retrics, more then likly they will last for a while but eventually your retics will prolly dye from the stress of the other stingray getting to big. (retics are funny like that)
