oh yeah, its hard to move my 40G, and i think the tunnel helps because the crabs choose where to hang out and they have more options when it comes to digging down from molts. they really travel between the two a lot. its a ferret tunnel, if you're interested in seeking one out.Lee56 wrote:I love the tunnel idea!
My 55gal is about as big as I can handle by myself (as in moving the tank itself). I've been wondering if there was a way to connect smaller tanks if I ever decided to expand what I already have.
