Now keep in mind, I have a bigger tank (20H) and I have one male betta, some guppies, neons, and Mickies in mine. They seem to get a long. With Betta fish, it depends on that fish. Some don't mind what you put them with as long as they have room, some hate anything with a tail like them, some just hate everything including rock and plants. Both guppy and neon are school fish, so you need at least 2. If you have the 6 gal., try 2 neon. If you have the 12 gal. try 4 neon. Keep them in the plastic bag (suppose to anyways) and if he freaks out and tries to kill the bag, he may not want anyone else in his big new tank. Good luck!
