I'm helping a friend with a group of R.uluguruensis and need some help. They are dropping like flies and I want to save as many as I can. Both the brevicaudatus and kersteni are doing well. But the Ulus are not. They are being kept in temporary tubs with substrate a low 15w bulb placed a few inches above the tank and some twigs and leafs. Ambient room temperature is between 68-75F.Twice daily misting and 1 week old crickets offered but not many are being eaten. Any help is appreciated.
