The Peaceful Betta is a great addition to a small tank. It’s calm and doesn’t fight with other fish. I’ve kept two together with micro rasboras and they get along well. The fish is active but not aggressive, and it enjoys the small flakes I feed it.

I was worried about bettas being aggressive, but this one is very peaceful. It fits well in a 5-gallon nano tank with plenty of plants and hiding spots. Feeding is easy with the flakes and frozen foods I use.

The fish is active and shows interest in the tank environment. It doesn’t chase other fish and stays calm. I’ve had it for three months and it’s thriving in a well-maintained tank with soft water.
