Martinismommy breed HM's HMPKs and maybe CTs.
Basementbettas breeds HM's, not sure about the others.
I know basementbettas has two females on aquabid right now and a couple spawns growing out.
I'm not sure if martinismommy has any for sale right now. nothing is listed on their aquabid page. She seems to workmostly with multi colored bettas.
both of those people are members here and offer great quality when they have some for sale.
I don't personally like chard56's bettas as breeding stock, but a lot of other people do and I hear he's great costumer service wise. Lots of colors and tail types available. here is chards aquabid page
