Attention: Although Astrochelys radiata shows good social compatibility in most cases, we strongly advise against socialization with non-species turtles! Astrochelys radiata has a particular hypersensitivity to certain microorganisms foreign to the species. If these are taken up in excess, it can come to the displacement or to the death of the intestinal flora. The immune system is thus considerably and permanently weakened and chronic and insidious inflammation of the gastrointestinal tract can occur. These foci of inflammation can also spread throughout the body and lead to generalized organ failure. Presumably, the low tolerance of Astrochelys radiata to alien microorganisms is related to the endemic lifestyle and the inhabitation of a very special, limited, ecological, niche.
Also, do not buy turtles from mixed-race stocks, because they may already be infected with various carnivorous pathogens! Please note that a socialization of different species is always an expression of limited space and ignorance of individual needs. A socialization creates not only an increased risk of contamination but also additional and unnecessary stress for the animals.
