What type of lizards has the least maintenance?
Honestly ive done ALOT of research and there are not many that do not require some amount of maintenance , bearded dragons need heat, uvb daylight timers, need to be fed every day if they are babies they must be bathed once a day and fed 2-3 times a day , they need vitamin supplements, they need certain sized foods , cut up veggies . the best thing you could et that is a reptile is a snake. They can withstand 65+ degrees depending on the type. I own a black milksnake which is called the poor mans indigo, they are curious, smart, and can reach up to 7 feet plus. I feed mine once a week and the food has costs me about 45 dollars which lasts me about 6 months. I would try searching in google for a reptile forum so you can ask people who already keep lizards.
