I was in my LFS today when I saw the most beautiful betta and could not pass him up, he is a gorgeous white colour and I think he is a delta (pics to follow I promise) so I quickly grabbed a divider and left with him. I noticed in the lfs that he was in the same tank with a female betta but there was no fighting, they were swimming along side by side. This was the same in another 2 tanks. the manager said these bettas were bred to look different to normal female bettas so there were no aggression issues between the males and females, has anyone ever heard of that here? I didnt buy them as a pair as I really didnt want to risk it and his tail looks like it has 1-2 bite marks but other than that he seems happy and healthy.
