My Japanese friend has given me two pairs of superdelta with halfmoon genotype two years ago. I bred them but one pair died and another pair which was turquoise survived, but their fries died after 15 days. I did it two times and the results were the same. I gave up and strarted cross bred them with my self developed deltas. The results came out very satisfactory, I have some super-delta bettas (show on the right). I selected and bred them four generations until I got a real halfmoon. One of them is on the bottom right.
        When raising shows quality betta you need very clean water and frequent water change. It is a must. I do change water once every week with aged tap water. Besides good quality water , container and it inside environment also play a major role in raising show bettas.
        The turquoise halfmoon below is a sibling of the super delta female above.
