(Super late!) Thank you! They're growing a bit slower than I would like, but I'll just chalk that up to being super busy while moving. Are you still doing any breeding as of late, by the way?
Hey aluka! Earlier this year, I purchased two of your traditional plakat females (1 marble, 1 cellophane) and had managed to breed the black marble one! The spawn is around 8-9 weeks now, and I'm quite surprised as I'm beginning to see strikingly similar colors as the bettas from your spawn. I've started a spawn log I'll be updating soon with much better pics of the babies, here's the link in case you're interested: http://bettasource.com/forums/topic/2150-green-metallic-hm-x-black-marble-hmpk-spawn/
