I have 4 crabs and heat them with a 40W day bulb and a 40W night bulb. I bought a double bulb hood from petco and, at the appropriate time, simply switch one on and the other bulb off. In my 10 gallon tank with screen lid, the tank is a constant 85%. I also bought a reptifogger to regulate humidity.

You could get an undertank heater pad or a heater emitter or just hang a lamp over the tank.
