CF live rock not cheap leh.... I heard.
will PM you the price.
Replica rocks advantage is that there is no pest, no dieoffs, nice shape.
no need to pm lah.
small replica (about 2 palm size) is about 3 red notes
large ones (about 18 inch length) is about 13 red notes.
Jireh does not display all the rocks outside. talk to the auntie boss and let her know you are looking for them.
She will bring them out for you to choose.
If you happen to go JM, let me know. I can go with you - stay near there.
GO's replica seems a little more artificial and the shape is not as nice imo.
