I've moved my tank out of the high-traffic kitchen, which I hope will help with destressing, but then it got down to 71 degrees (as measured by a digital thermo-hygrometer about 3 inches from the bottom). I use two UTHs under a 10-gallon tank. My husband insulated the tank and put a moon light on the side, and it's now up to 78 degrees. I read on a recent post (can't remember by whom) that actually temps in the 70s are too low - the crabs should really be in a habitat more like the 80s of their wild homes. So should I leave it around 78-80 by the thermometer (assuming it's warmer under the substrate), or turn off the light and stick with the insulated UTH heat?

My tank generally ranges from 78-80 during the day and 75-77 at night. I think your tank should be fine at 78

Really? But I'm pretty sure I read somewhere that 82+ could be really bad for crabs. T__T;;;; ACK. It's so confusuing for a newbie...Does anyone keep them in the 80s? And does everything go okay? I've been keeping mine in the low/mid 70s becuase I was afraid of cooking them...
