Nano-appropriate goby or blenny?

[Fish]

Hi all,
I have recently had to remove the baby clown from my nano as there has proven to be too much current inside the little tank and a fish that spends its time in the water column has no place to rest. For this reason, I am looking at getting a fish that can "sit" on the substrate instead. Would a bi-color or midas blenny work in a small 2gal nano? If not, can someone recommend an apropriate "sitting" fish?
As always, thanks for your help!
