Well your girlfriend has wonderful taste in fish. :)
Just a note for breeding - be 150% sure you are ready. I hear betta-fish breeding is quite difficult for $10 fish. Especially the costs. The main difficulty being housing 10 - 60 fry, usually on the first try. That's 10-60 containers, and water changes. Males and females occasionally end up killing each other if done incorrectly, or just some bad incompatibility. There's so much more to it as well...I'm not discouraging you, I just hope you are VERY ready! Good luck if you very interested!
