Simple frag plugs

[Fish]

I think you would actually end up with a decent number of polyps if they encircle a one-inch-long cylinder with that diameter - I know I learned a formula for surface area one time...
They would probably grow faster too because there would be circulation from all directions - like zoos growing on old acro skelletons!
I don't know if I'm the only one, but I hate frags mounted on agrocrete plugs! They look good but it is a bugger to take frags off of the plug because of all the crushed shells - pretty tough to cut through with a razor blade. JME.
