How are you offering food? I find that a lot of my scorps will not eat in my presence and/or during the day. Just leave some prey items for it to eat and post again in a couple weeks if nothing has come of it.
Also, don't forget that a 2 month cooler(10-15F) in the winter does them good too. Douring this time they will eat much less. Is it possible that where you are keeping them has been a little cooler lately?...If that is so they will eat less.
Yeah...that might be good....I usually reduce the wattage of the heating bulb I use and the temp goes down about 10 degrees.
My collection is in a closet that has no door but I put a clear shower curtain in the opening. Right now even when its cold outside...4x60W lightbulbs keep the closet at a good temp. I may turn the light off for the H.arizonensis tank when I do my cool period. I'll have to measure the temps to see.
The heater doesn't have a wattage label on it, but it's the smallest of the Holmes brand ceramic heaters. I think I paid $20 for it at Walgreen's I have it plugged into one of the cheap plug-in thermostats from the feed store and keep it set around 85 degrees, with a slight drop at night. I think it would also work pretty well plugged into one of those appliance timers once you figured out your heating needs for the room. I don't think it's expensive to run since I haven't noticed any significant increases in our electric bill since I've been using it.
It does heat the whole room, with cooler spots on the far wall. It's a floor model so none of my pets are anywhere close to it. It keeps the ambient air temperature in the mid-80s.
I put heat-loving species on higher shelves and more temperate species on lower shelves, which creates a heat gradient of a few degrees.
That makes scorpions "top shelf material." I don't know why that popped into my head.
I also use a space heater for my room. It is situated on top of my monitor lizard's enclosure and ducted into the enclosure. That keeps my monitor lizard's base temperature pretty high and the rest of the room at reasonable temperatures.
Kugellager, if your worried about electricity, as i am, buy an oil filled radiant heater. Mine cost $70 canadian, and heats the room very very well and is thermostatically controlled. It heats the oil inside, then can turn off for a long time because it retains heat so well it continues radiating when its turned off for a long time. Also they ate 100% safe of starting a fire just about, and make absolutely ZERO noise.
If you want a picture of mine just ask.
I`v got 4 Emperors about 1 inch! They havent been eating for about 14 days :? There`s a little criket in there with them now, but they are not interested... Should i take that one out, or just leave it for them to eat if they want? It`s been in there for four/ five days now...
The temp is around 26- 27 c (Dont know F, maby around 80- 81?) during the day, a bit cooler in the night. They also have water, and i mist about twise a week....
