So with the $1/gallon deal going on at PetCo, I figured now would be an awesome time to get 2 new bettas! The thing is, though, I've never had more than one at once. They would each have 5 gallons to themselves (Lotte in her 5 gallon, and the other two in a divided ten gallon), a heater, filter, decorations, and all that. I'd feel bad if I started to favor one over the other, though. So my question is, would it be "bad" to purchase another betta (or two) if I already have one?
