u/Peenard-

About a month ago, my crabs tank mate has passed. Ever since my remaining crab has been more lethargic and scared as I believe the other made her feel more comfortable. Is it okay to leave her as a single for a month or 2 more while I work on making a tank topper?

I’m currently building my tank topper, and I’m wondering how do I keep the humidity in? The top tank is an exo terra that has ventilation holes near the bottom and a slight gap between the doors. How do you stop this from leaking heat and humidity?
