Happy Birthday and welcome to the HCA! You will find a lot of info here and very friendly people!
Your tank looks amazing...love all the little plants! How many crabs do you have in there? Sorry if you say so in your video, but I can’t currently turn the volume up.
After admiring how beautiful it looks, my attention went straight to the substrate and gauges. Lol, can’t help it. You may know these things and they certainly aren’t meant to be judgy (I kept mine in a critter keeper for a week before I stumbled onto the HCA). You’ll want 6” of substrate or 3x deeper than your largest crab, whichever is more...also very important to make it sandcastle consistency so their tunnels/caves will hold. They need the deep substrate for molting. Then, I always shoot for 80/80 humidity/temp. I have found that they are more active when it’s warmer! You may already be working on these things, but figured they were worth a mention...feel like they are 2 of the most important things to be mindful of.
What a great Bday present! Have fun with it! I’m sure some others will chime in as well.
