Mantillia x Motoro

[Bigtdotcom]

Hi guys I've been browsing some local (sydney australia) ray forums and a lot of people seeming to be selling mantilla x motors or leo x mantilla even seen some labeled as 3 way hybrid.

What size could I expect males to grow to of the mentioned crosses?

With hybrids it could be anywhere on the spectrum from 8"-28"+

Males will always grow smaller then females I would expect under 18" full grown but that is a educated guess
