got some new Bettas today, was wondering if you could help me with names?

First one is a crown tail Betta, head and body is dark blue, almost violet, tail and most fins are dark red.

Second one is a long tail Betta, golden in color.

Third one is also a long tail Betta, red in color.

Honorable mention: I had five 5 gals set up for 5 Bettas, and the shop got the delivery today. I also had 2 more long tails. One was white with hints of peach and red color on his fins and tail, very different color. The other was also a tri color Betta: blue head, red body, and very light blue tail ends. Unfortunately, these 2 could not survive the ride home. =( Don't know how they were treated when they were being packaged at the supplier.
