I am excited for you and your kiddo! I have had a betta sorority for three months. Did some reading on another forum.......cannot recall which one.....and they said not to use clay pots with holes as bettas could become stuck in the holes.
I rolled my eyes. These FISH people! I have had pots for three months with no problems. Got up to get a cup of coffee, glanced in the aquarium, and you guessed it. My Deca was deceased and so firmly wedged in a hole I had to physically pull her out. Her tummy tissue was literally gone from straining.
I removed the pots! The forum said to use marbles and aquarium sealer to block the holes; they recommended one on the outside and one on the inside. I need to purchase sealer and do this.
I got my girls young enough to go through the holes but...they grew.
Good luck!
