i added a yasha goby & pistol shrimp to my tank yest. the shrimp is tiny so i doubt ill see him for a while, the goby on the other hand is small but not so small as to be missed. i havent seen it at all. i havent had a goby before. do they normally hide after acclimation. im worried it might have died and i dont know it. he was out for a little while after i added him, but since then he is no where to be seen.
