Motoro x marble motoro???

[motoro13]

So I have 2 motoro x marble motoro stingrays about 5 inch disc. They are about 14 weeks old now. My question is will a marble pattern develop more with age and maturity? I do see some marbling pattern on the female.

Thanks in advance...

its a 50 50 chance

I know a guy that breeds this combination,some of the pups display a degree of marbling early on but as they grow this fades out completely.
Its all down to genetics really,if one of the parents(Marble) is an exceptional example then there is hope.
Good luck!
