I recently took in a previously owned bearded dragon. I was told he is around 1 year old and he is about 15 inches long. He came in a 55 gallon tank with two lamps (one UVB almost burnt out and the other was a regular Great Value brand lightbulb). All that was in his enclosure was a rock/hide house about half his size, a heated rock, and a food bowl. The tank was disgusting and smelled awful, the reptile carpet covered in freeze dried crickets and mealworms. I was also told that he was regularly fed Dubias and vegetables “once in a while”. I’ve had him for 5 days now. Since, I have upgraded all his lighting and provided a ceramic heat emitter as my house gets colder at night. I replaced the reptile carpet, cleaned the tank using white vinegar and hot water, kept the rock/hide as a basking rock and so he had some familiar items. I provided a new water bowl, food bowl, a hide large enough for him to fit inside, and some fake plants. I had little to no knowledge of beardies before I got him, but I could not stand to see him in the condition he was in any longer. His previous owner was happy to surrender him to me but did not give me a ton of info on him in regards to how socialized he is and if he had been able to roam outside his tank. His tail is long, and it seems hard for him to pivot in the tank as the 55 is tall and thin. I’m thinking of getting a 40 gallon breeder tank with front opening doors. Is this a good idea? He is relatively active during the day, but he is still getting used to his new home and glass surfs often. What basic advice can you give me? I’d like to know as much as possible, and maybe some specific tips for owning a pre-owned beardie.
