Theres only one diamond in those pics , both pics are the same fish. Well at the moment a 13ins Peru black would cost roughly £300 , ( if you know the right importer) , dont forget theres a few thousand miles extra shipping involved and not many at that size make it alive this far from Peru , i dont think there are direct flights to the UK but there are to Germany where they are greedy for them! So at the moment i dont think thats too bad for UK with the exchange rate. 6-7ins piraya are £80 store price. I sold the diamond about 2 years ago, for some reason it didnt grow in the year i had it, and wasnt much of a feeder, they are pretty fish tho not as heavy set and powerful as a black .The first of those Perus blacks grew from 10.5ins to 13ins in 3 years. The second black made it from The Nanay, Peru at 14ins 1 year ago, cost £300. Cheers
