Super Glue???

If you do the pillars correctly, the goby cant move them. You dont just stack them. You drill a hole thru them and use an acrylic rod placed through them to hold them up.... There a lot more to it, they will take way to long to type, and I dont wanna hijack this thread.

If the surfaces are rough enough give the hot glue gun a shin dig.
