Opinions on Goby for tank

I'm looking to add a goby to my tank at some point in the future. I love the diamond goby but have heard they can deplete a sand bed. Is their a goby out their that does some sand sifting, has a great personality, and won't totally deplete my sand bed?



If it helps I have a 75 gallon, with 1-2" sand bed and 80lbs LR
