Is this ok for my betta?

I have him in a vase that holds a little over 2 gallons and a bamboo stick in it. The roots dont take up much room and he cont get stuck in them or anything. I also have a few marbles at the bottom. My room is very warm so the water temp is about high 70s low 80s. Ive been keeping up with water changes. The vase has a very wide top almost like a bowl and its filled with bubbles hes made. Im fedding him pellets and brine shrimp
