Alright so it looks like they are happy we changed the substrate and whatnot. We'll look in to a glass aquarium, out biggest issue is the height of the tank.
Hey there, we upgraded our tank to a 10 gallon glass aquarium! We also picked up a bunch of new shells, gonna see if the big guy will move out of his current cracked/broken one. Gonna look into getting a hemp net too! http://imgur.com/a/CM8sx
