Too hot?

[mushwoom]

I live in Puerto Rico and will be getting my first crabbies in the next few days! The room I'm going to keep them in has no a/c and since we usually have the same temperature (between 80F-85F) all year, I don't plan on getting a heater. My question is, sometimes it gets up to 90F in the room (my bathroom). Would that be too hot? There are obviously native hermits here and the make it...But how can I make sure my crabs don't get too hot?

90 would be ok as long as it's not for an extended period of time or if they have cooler areas to get to if they want/need. If you think it's climbed too high for too long, you could place a frozen water bottle on top of the crabitat to one side to provide a cool area. I do this for my crested geckos during warmer months when it gets a bit too warm for them. It should work the same way for the crabs.

Air movement, shade, and moisture combined have a very dramatic effect on temperature. You're in an area where the humidity is already high enough for them, so if you are ever worried about the temps you'd be fine to put a fan on the tank. Most of us don't have that option because where we live it's too dry and a fan would dry them out even more. 85-90 degrees is where my tank sits in the summer since we generally don't use the a/c, although there is a gradient in the tank and it does cool off a bit towards the bottom thanks to the wet substrate. If you set the tank on tile that will also act as a hink sink and cause the substrate to cool off more than the air around it.
