Brumation:  54-62°F (12-17°C) for 2-3 months

Known Mutations: Albino/Amelanistic, Hypomelanistic, Patternless
Hypomelanistic 100 Flower Ratsnakes are being bred with some regularity in the states in a co-op between Karl Krumke & Stan Grumbeck. The original hypomelanistic female is an animal that has been in Stans collection since 1995, that a friend of his brought in through a California importer. The male that first bred her was a captive hatched animal that came from a clutch Kameron (Bushmaster Inc.) hatched that was laid by a wild-caught animal. That male got up over 8 feet long and was a massive snake. 
Another hypomelanistic specimen is known from the late 1980's and was in the collection of Chris Newman (UK), this animal sadly died before he could pass on any of this genes.
Reduced Pattern / Green / Patternless O. moellendorffi were bred for the first time by Terry Neset (USA) in 2011, a project that took nine years to completion. 3.4 visuals were produced from hets, proving the trait to be simple recessive.
Captive Bred Localities:
Natural History:  Inhabits altitudes of 50 - 300m. Orthriophis moellendorffi lives in a terrain of karst topography, a sparse landscape of crevices and caves made of limestone.
