I paid like 6 bucks per lb on that piece I think over at aquatica I got it because I though it looked cool it only had like 5 little Ferns on there now it has like 20 they just started coming out from all the holes it has inside. Looks cool tho the biggest one is the one in the left side top corner its about the size of a half dollar coin. Doesn't look so big in the pic tho.
