Looks like one the LFS had, I thought it was a monti,they said it was a goniopora.

Goniopora most likely

It's Goniopora all right, but to determine the species you will have to go by an exposed corallite. Here are a few possibilities.

Goniopora tenuidens http://coral.aims.gov.au/factsheet.jsp?speciesCode=0208
Goniopora minor http://coral.aims.gov.au/factsheet.jsp?speciesCode=0199
Goniopora stutchburyi http://coral.aims.gov.au/factsheet.jsp?speciesCode=0207
