Where can i find Boraras maculatus? (Dwarf Rasbora)

[Jodah]

Would love to get 3-5 of these little guys for when I setup my 5.5g as a planted tank. Problem is I can't find anyone locally, or even online that sells them. Also how compatible would they be with a male or female betta?

I wouldn't suggest them for a smaller tank, despite their tiny (very cute) size. They can be very sensitive (sadly all of mine died despite perfect water quality in my tank, just from the stress of moving, I think), so go at least ten gallons if you can. If not, make sure the tank is well-established (at least 6 months).

An aggressive betta may harass them, but due to their size calmer bettas will ignore them. My female Athena was fine with them.
