More questions:
How do you measure your humidity? Or do you just judge it by site? Some I just know it's where it should be by looking at what the humidity is in the room currently. I do have some humidty gauges in the room to see what the rooms humidity is. I currently only keep 1 temp/humidty guage in any of my T's tanks and that is in my Theraphosa stirmi's tank. You want to make sure without a doubt the temps/humidty is spot on with them. I use accurite humidty and temp guages (same ones we use for our snakes). What should I look for to tell me that the humidity is right? That's hard for me to answer. You would need to at least know what the humidity is in the room until you get more comfortable with things. You should be fine with a little water dish (if the T is big enough for one) and possible mistings if you needed it to get the humidty where it needs to be.
Do Ts dull out before they molt? Yes. He's looking a little dull and has refused food the past couple of times I've offered. I'm wondering if I should be expecting some molting soon. Probably
Ummm I thought I had more but I can't remember. Thanks again for all the help and answers. I can see how inverts are kind of addictive...I'm obsessed with p. metallica but I'm pretty sure that wouldn't be a good second T...
