I was at the LFS today checking out some remodeling they're doing (apparently they're adding an entire section on planted tanks) and noticed they were selling a black betta that they labeled as "rare". It was $15 which seemed pretty pricy for most fish I buy much less bettas but it was a very beautiful fish. I don't have any pics, but it's a smaller betta (or possibly just a juv fish) doesn't have the long flowing fins of fancier bettas and is jet black. I was a little intrigued as I have 5g and 10g tanks with no occupants at the moment. How rare is the black betta anyway? Is caring for it any different than your average betta?
