Koji, I'm a huge fan of your breeding operation you have got some first rate selective breeding going on! Those are unbelievable Diablo Reds and I want about twenty, and some great cross backs, I want another twenty.
On an earlier post I mentioned that I have got a poster with some purple red arowanas and was led to believe to gain that kind of purple with red hormones and dyes were used. Looks like that is not the case. Do you have any pictures of any adult diablo reds and how much purple coloring do they acheive as adults.
You will get to see more base colour once they are out of the water. If they are in the tank, unless with the right light setting, you wont get to see this much obvious colouration.
