Except bettas aren’t herbivores. They need better food than that. (Bugs,worms,etc). Kinda like chickens that way.It has a little plastic drainage dish for a flower pot with a hole cut in the middle. This holds up the top of the plant . You don't have to feed them but once a week because they eat the roots of the plant. Lift up dish & put a pinch of food in. Water stays clear because plant absorbs poop as fertilizer.
