I would have to agree with that as well, I LOVE urosI'd go for a Uromastyx... those guys are so neat, and absolute sweethearts.
If your looking for a lizard that can live in a 60 gallon or less tank and is 1-3ft and looks "meaner" then a Bearded Dragon is your best bet. Any other lizards I can think of at the moment need larger enclosures.
You can always get yourself an Ackie spiney Monitor (Varanus Acanthuras ). they can be kept in a 40 gallon breeder.
Are there any alternatives to bearded dragons then, like still meaner looking, but not HUGE. Less than a 60 gallon tank or so
Something between 1-3 feet
What about something more manly and badass looking, that doesnt get crazy BIG.
