A Question about led lights and substrate and more..

[hermityhannah]

1. To give day/night effect, i use a led light during the day. It is 2W and very tiny. But my crab seems to hate it.. It isn't active when its on and goes to the darkest parts of the tanks.. But when I turn it off, it seems to move around more.. Should I stop using it..?
2. I currently use cocofiber solely for the substrate. It's about 13cm (it's really the max I can do...) The thing I would like to ask is how should I get the consistency(?)to be moist enough? Especially the substrate at the bottom of the tank..
3. My hermit crab does not burrow.. My hermit crab is not going below or in the subsrate.. Only roams outside of it.. Could it be a substrate problem..?
It would really mean so much to me if you could answer any of these questions! Hope you have a great day (or night!)

With the light: Crabs are nocturnal so he's just finding a place to hide and sleep in the day, just like you would do at night, no issues there.
Substrate: Crabs need deep substrate to molt. Most of us use a 5-1 mixture of play sand and to eco earth the get the right consistency. Make sure it's moist but not damp, sandcastle consistency. You need a minimum of 6" (about 16 centimeters) or 3 times as deep as your largest crab, whichever is deeper.

The 12 hours day/night is important to the crabs health. That 12/12 helps them regulate their molting cycle. We have an occasional crab or two that will stay out during the day. More times than not ours venture out within 15-30 minutes after the light goes out.

Questions two and three go hand in hand. Your crab may not burrow because it can't or is afraid to. If it's too most the cab may be scared to dig into water. It may think it's too close to water and a ride or rain may move in causing it to drown. Too dry and the crab won't be able to make a tunnel so it can't dig.

The easiest way I tell if my sub is good is to poke a finger all the way into it. When I pull my finger out the hole should hold it's shape and not collapse.
