He can try but I doubt he will be succesful. It has been tried many times even with lab stimulation and such to no avail. Hopefully he has a nice outdoor pond he can try to breed them in. That would be awsome though if you did get them to breed in aquarium. That would be a major mile stone in native keeping.
I live in Tn where they are native to here so I can throw them in my pond in a couple months with Plenty of anacris (aquatic plant spelling?) and let them over winter this year and see wat happens next april or may
