Firstly I should say I have never met or dealt with you and that I think all of the speices you have imported to NZ are great for the hobby and this wasn't personal at all, no matter who had started that auction if they had publically suggested creating hybrids I would have done the same.
Hey yeah there are plenty of discus types but they are all strain's of the same fish ie they have the same scientiffic name therefore there are no problems with breeding all the strains together to create different ones.
Your example with cockatoo's is different to what you have suggested orange flash cockatoo's tripple red's and your wilds are all the same fish, all of those colour varieties have been developed from wild strain so they are the same fish..
To me you have imported 2 different fish, they have to be different as they have different sc. names and that was what they were imported as if they were the same they would have the same sc. name and strains or colour varieties as well. Yes they will be similair as they are all appisto's but different, alot of tetra's or danio's are similair should we just cross all of them?
IMO we have a few small number of descent fish in NZ and you as a professional breeder should not be suggesting cross breeding 2 different species and potentially ruining both species in NZ.
