My beardie is a baby and right now is in a 10 gallon (he's only been in there a week). I'm going to get a 50 gallon and set it up nicely for him. He is only about 5 to 6 inches long as of now....is a 50 gallon too large for a beardie this small? If I get the 50 gallon within the next week should I leave him in the 10 gallon for a little while until he gets a bit bigger? I'm not sure of the proper protocol.
