What do bettas like in their tank?

Bettas like a variety of plants, toys, and decorations in their tank, including:

Make sure all ornaments and toys have no sharp edges that can hurt the fish.

To avoid contaminating the water with dirt and harmful microorganisms, clean everything with cool running water before putting them in the tank. Don’t use soap, as the residue is toxic for betta fish.
