My tortoise is a russian tortoise named Albert who I just got recently. My school I heard has a science fair and my idea for it was to find out what type of music Albert likes. I am going to use a small Bluetooth speaker. How would I gage if he likes a certain type or not? I'm going to make sure it's not loud and there won't be any stressful music like heavy metal. I'm planning on trying pop, disco, AC/DC, reggae, classical, and nature sounds.
