I have been wanting to get a Columbian Rainbow boa. I have been doing research here and there on them. I have a setup but someone told me it wont work. Here is what I have : a 40 gallon glass tank and stand, with 3 inches of cypress mulch in it, a water dish on one end, a bowl of water on the other end, a log hiding spot, a vertical piece of driftwood to climb on, and a 100 watt ceramic heater, and a digital thermometer/hydrometer. I am having real problems with the temps and humidity. My tank does have a screen lid, I have tried covering it with plastic, I have a humidifier in the room, I have the water bowls in the tank and have even tried misting the inside of the tank. I have been told that the ceramic heater dries out the air way too fast thus keeping the humidity too low. I also have a problem with getting the temp right. it seems like the spot where my heater is , its about 85-90 degrees but theres not much of a gradual change, like the middle of the tank might be 60-70 degrees. Should I just scrap what I have and start over? or should I find another snake for my setup? I was really wanting a Columbian Rainbow Boa. Any help would be appreciated!!!!!!!!!
