lets just say, live aquaria has a very similar hammer in their divers den right now. they priced it at 149 dollars. and theirs is only 2.5 inches.
mine is 7 inches in the pic... and it still isnt fully open yet. i got an amzing deal on it, so i HAD to get it.
i also have never seen an aussie hammer that is actually orange. most are just either pink, or bright green.
