Fish Boraras for Shrimp Tank

I got some nice and gentle little boraras fish for my shrimp tanks.
I like it in nice red color. Well, this photo could not present their beauty (my camera's limit).
About the seller, they have very nice fish, and very professional package, but they charge way to much shipping and packaging fee, which I think is really unreasonable. Anyway, I receive this little guys safely, that's of the most important thing.
