Bumble bee tuna is his name hehe And well he yawned or fixed his jaw and still being a baby hes got extra skin so he kinda shudders trying to crawl on my skin, So he did the yawn this his mouth was slightly cocked open, and I dont know if he fell down or struck at me cause after that his mouth was fully closed. I put him back in his tank just encase hes being a grumpy boy
