Welcome to the forum! The tank, betta and black neons look sweet! The rocks look really cool, and your really on a good start, cause this your first tank you said correct? If so, well done. Most newbies that set up their first aquarium learn the hard way by buying the fish and tank the same day. And set up the tank with no live plants and brightly colored gravel LOL. Me from experience with that lol. Again, glad to have you!
