Sebastian is my new betta. He's a beautiful dark blue with red tinges. I love home and as for now he is alone in a one gallon tank. Hubby has offered to buy me a five gallon this weekend, but it want to maybe add a companion. I've been reading everyone's posts and I'm wondering if adding a Cory or two, or maybe a plicostmus (spelling) to the tank might be okay? I'm just not sure what to make of Sab...he seems withdrawn and is shy. Never seen a shy betta!
