Well I know its not a JD, but if it was assorted African, most of those that come sold that way will intermate with similar looking African cichlids that you can pick out from the same kinda assorted tank... I'd pick up a few if they are as cheap as they are here (few dollars each) and wait for a pair to emerge, then return the rest or if you'd like keep them... you may also want to get a female for your jewel if it doesn't have one already as the pair your trying to create will over power a single jewel. Good luck, hope this helped
