If it has fans', it's probably a bambo or fan shrimp.
They need salt water to breed, usually live a decent life if there is food. They are a filter feed, they put out their fans and eat from stuff collected in the water. Usually people see them perched on some wood near the outflow of a filter as the current is pushing stuff in the water for them to munch from.
Fairly peaceful shrimp, not a food hog like amano's or ghosts.

If it's a shrimp using "fans" to feed and he is looking for food on the substrate that means he is starving. Increase water flow and provide him with ways to sit in the water stream and filter the water. I personally would be careful with azgardens but to each their own.

I'm going to amend that a little. Even among the chiefly filter-feeding larger fan shrimps, scraping can be an important feeding strategy and isn't necessarily an indication of starvation. (Exactly how much depends on species and flow conditions.) A. pilipes are found in a rather wide range of flow velocities in nature, and in captivity they're often just too opportunistic not to pass up substantial fare like pellets or gel.
But yeah, in the aquarium this behavior is frequently a giveaway of insufficient current or too few suspended food particles. Having a powerhead directed at a piece of hardscape that they can perch on is always appreciated.
