They can be kept together without risk of crossbreeding, the size of the colonies you plan on keeping will dictate the size tank needed since both species utilize the same area of the tank.
I had no issues with 15 of each in a 125 with lots of rock, both groups always had females holding. FYI I have heard many others reporting that they found their paracyps stressed by the cyps.
