Hey everyone
I am in the middle of creating a second tank to house my gerbils. My plan was
to connect the two tanks  using PVC piping. Can my gerbils climb straight up
these pipes? Is there someway to texturize the inside of the pipes if they
can't?
If not does anyone have any other suggestions to connect the to tanks. By the
way, one tank is 10 gal and one is I believe 20 gal.

Thanks
Erica
