Hello, I recently bought a Half Moon Betta named Moony. He's a lot more active and fun than I expected and I think I may be a lifelong Betta lover! He's just a dull grey color, but in the light he has streaks of blue, green and purple. When I bought him, I noticed his tail fin was horribly tattered. I don't know what the pet stores do to old Bettas, but I knew no one would take him. I brought him home and he's been a happy Betta ever since. His tank is 2.5 gallons and he has no other tank mates. I gave him a fake leaf to sit on and a little floating ball.
I am very tempted to get another Betta, but Moony's enough for me for now.
