Its a Bamboo shrimp! Aka wood shrimp or Singapore shrimp. You can see my beast below.
I've a new one in my tank; my previous one had an unsuccessful attempt as accelerater evolution (be sure the tank is WELL covered!). They're filter feeders; they don't eat detritus persay like ghost shrimp, or algae like amano shrimp, but eat the micro organisms found in the water and on the substrate. Look carefully and see if he has one larger appendage in the front, sorta like a claw. If so, its a boy :) They're supposed to get to be around 3 inches long; mine arrived at 3 1/2 inches tho
LOL
Where did you get him?
I'm not exactly sure how big dojo's get; check
