I spawned my male Loki with a female MG today. Both from Basement bettas actually, I bought the female 6 months ago and the male 2 months ago. They spawn looks pretty good sized so far and daddy is doing a great job watching. This was one of the easiest spawns I have tried to do in a long time. I dropped them in and within 8 hours they were spawning. The male is actually a good deal younger and smaller than the female, however she really wanted to spawn so she didn't give him a hard time and she even picked up the eggs like a male. The spawn tank is a ten gallon btw..
The father is really camera shy so the pictures are bad sorry.
And the mother
