Welcome to the forum, Mini! Glad to have you and Angel (I assume that's your CT name, as it is in your signature?) here with us! I would love to see pictures of your betta and his tank. I always enjoy seeing everyones fishies! I love halfmoons and that will be an exciting addition for you. Sound like you've been bit by the betta bug. There is lots of good information here on tanks and dividing them, so learn as much as you can!
My lovely bettas are: Dagger, Egg, Salsa, Marble, Augustus, Miles
Puddles, Oz, Nate, Monkey, Picasso, Feng, and Maui
