HCA: Hermit Crab Association

I recently got a 12" x 12" x 18" tall exo terra tank Their old tank was a 20 gallon long tank (the 20 gal is not an exo terra, and I don't know the exact proportions, just that it's a long 20 gallon), I'm trying to decide which one to keep. The 20 gal is not as tall but its longer, so the substrate in that tank is about 3 inches high. My smallest hermit crab, Beth, liked that there was a long area of substrate, and my medium size hermit crab, Boba liked climbing, but there wasn't a whole lot of things to climb on in the 20 gallon. My newest and largest hermie, Crunchy, doesn't really care either way as long as there's some substrate, some climbing things, lots of coconut to eat, and his favourite coconut hut With the exo terra tank, there's lots of climbing stuff and even a 3-D climbing wall/background! (I caught Boba climbing up the wall yesterday, I walked away for about 5 minutes and when I came back he was climbing upside-down on the lid of the tank ) For Beth the substrate isn't as long, but it's deeper, more like 4-5 inches deep, and like I said before, Crunchy doesn't really care as long as there's stuff to do and all his favourite coconut things

Would the exo terra tank be too small, or do you think it would be okay because there's lots of space to climb?

I'd say keep the bigger one. that exo- terra would really only be the equivalent of a ten-gallon tank, and with hermit crabs', height is a plus, but you what really matters is the amount of molting room you have.

I also have a 20 long, and I love it!

I would add more substrate to your tank though. You can get a 50lb bag of play sand at Lowes/Home Depot for five bucks, easy

But if you can keep both the exo-terra and the 2oL, you could maybe add a topper to the 20! that way you get the best of both worlds!

Thank you, I'll try that! I originally wanted to do a topper but I couldn't figure out how to attach it. Next time I'm near Home Depot I'll try to get some sand/substrate

Great! I've never done a tank topper, but I'm sure if you wanted to do it you could look up how.

Crab Central station has a great tutorial video on how to set up an Exo-Terra tank as a topper on YouTube. I followed their suggestions with great results.

Thank you guys! I couldn't find anything online about exo terra toppers or even normal toppers, I'll definitely look at their channel (:
