So I was surfing AquaBid again... I do it when I have nothing else to do... And I found a place in my area (Portland) selling them! Not only that, they are selling wild types.
This is the list of what they have:
Betta splendens - male and female - $3
CT - male and female - $4
HM - male and female - $8 and $10
Brueni Betta (betta macrostoma) - $180 a pair
Golden ninja betta (betta strohi) - $16
Green mask betta (betta pugnax) - $8
Green moon spot betta (betta uberis [Kubu]) - $16
Green spot betta (betta cocinna) - $5
Peacock betta (betta imbellis) - $3.50, 6 for $18
Red cherry betta (betta channoides) - $15
Strawberry betta (betta albimarginata) - $16
I had no idea that they carried such a variety or that they had so many wild types there!
