Compared to uros, ackies are a really big thing to take on. they need temperatures that are just about as high as uros but a lot more space. they don't just need hide spots, but also things to climb on, with plenty of different height levels under the basking spots to thermoregulate. my yellow ackies are about 15" and 19", all muscle. if you think a uro can motor if it wants to get away from you, you should see a monitor. their diet at our house consists of approx 2 pinkies a day, with some crickets thrown in for variety. dusted about every other feeding. the only other thing they ever eat with us is maybe 1 superworm for a treat or, if we can't get pinks or crix, some ground turkey, but thats a last resort. the rodents are the best for them, and the cost can definitely rack up if youcompare it to what it costs to care for a uro. our ackies are about to move into a 65 gallon tank which really should be considered the bare minimum when housing a pair (we don't have room for anything bigger). at LEAST 6" of a dirt or dirt/sand substrate is needed, the more the merrier. they need big water dishes and fresh water all the time. etc etc etc.
all that said, i adore my ackies. they certainly are more exciting to watch, especially when they eat! ours are exceptionally calm and like to crawl up on our heads. they do not, however, take much to holding, rather they let you sit there while they climb on you. but you can't take your eyes off them for a second, if i walk too close to a counter while the girl's on my shoulder she takes a kamikaze leap for it. they are very tough and sturdy lizards, but an expensive undertaking. you can maintain ackies on mostly crickets, however it can really stunt their growth. the rodents don't stink as much either, especially if you buy frozen.
hope that helps, let me know if you need any more info.
