The belly on my bonsai some say sb but measurements meet Bonsai classifications is pretty large and swollen looking too. I’ve tried not feeding for 2 1/2 days and he pooped everything out and his belly barely went down in size lol. I figured it was due to his short body. Anyways i can see his belly swell just slightly when i feed him. He’s only 3 inches at the moment, i hope he turns out amazing as an adult. Heres a pic.
