Moist substrate is the norm for Chilobrahys, but fimbriatus is an exception for that genus; there may be others.
Why does Chilobrachys fimbriatus come from an arid region of India?hehe
This spider grows quite large 7-8" and will be very defensive as an adult!Post molt they are a brownish coloration and freshly molted will be a nice black color.In my opinion they are likely Chilobrachys dyscolus!From what I understand this locale in Thailand has very large individuals but I have also seen some quite large dyscolus available to!Keep these the same as Haplopelma.Deep substrate to burrow and also keep it moist!They are very hardy spiders and easy to keep!Just watch your fingers!
C. fimbriatus come from tropical forests in the Western Ghats... I keep mine moist and have never heard that they're an exception in terms of moisture.
Well, I've never been to India, but have seen advice given numerous times to keep them on the dry side. I assumed some of those people knew what they were talking about, but not necessarily.
Keeping tarantulas on dry or moist substrate can often be a heated debate on this forum hehe!Some say to keep all tarantulas on dry substrate with a water dish!
