Good shot! I know how hard the nugget can be to catch. Your's getting more friendly yet? I've had mine for over 6 months and he is just now starting to show himself. You really have to sneak up on mine to get any pic at all.
Edit: almost forgot to say, there are many different ones too. Small spot large spot etc. Mine has been called a queen gold nugget by some. I think it's a medium spot, and it looks like this is the same as mine.
