dont beat your self up. my first beardie died after 3 months, the vest suspected impact. which makes sence he used to dive off his stick into the side of the tank multimple times a day. usualy they do it a few times and then they smarten up... but this little guy just wasnt bright i was pretty upset because i really liked the little guy and wanted him to become large and beable to wander the house... but he didnt make it. i got a new one a few weeks later. and he is doing quite well thankfully.
