Thanks for the cites info! but i have some doutb, for im not an expert
There're many info not making sense, for instance:
"...There are some breeders who dig up a big earth pond and throws in whatever fishes they have in their breeding stock..."
In Singapor or other breeding farms countries, Asian Aro are lower cost than in USA, Canada, UK... but, but, still not cheap. Breeder invest some asian aros cost money, why they drow in whatever they have in stock, which won't help any better.
Let's say asian aros are very cheap over there, they don't care about the cost of the asian aros, why they drow in "whatever" which won't help any better.
Further, only arowana would mate each other, then what's the problem as long as they all healthy????
