This price discussion always amuses me.
People are happy to pay £500 - £1000 for a run of the mill farm bred Aro, £20 000 and above for a "special" one but something which is still farm bred and selectively bred at that - hence all the deformities you get.
These Datnioides are 100% as nature intended them to be and nothing I know of comes close.
Of course, thats entirely down to personal preference/choice.
