That would probably be Kia (coolbettas) on Ultimate Bettas. That's where I got my HM. Since I just bought the 1 male and picked him up, I only paid $20. He usually sells pairs for $35 plus shipping or single males for $25, I believe. I've seen his setup since I picked up my HM, and it's really nice and clean. All his bettas (HM and HM plakats) were very nice.
