I would keep a close eye on the red humps when you get them.Males can be extremely aggressive towards females once they reach maturity.They often kill females and can become a real pain.There are lots of other geos that are less problematic.
Went to my LFS and didn't see any altis. Also really do like the red humps. Any recommendations on other combinations that would work? As opposed to 1 male 3 female. Like I said, originally I said that because I thought males were pretty aggressive toward each other.
