Tossed a Harlequin shrimp into my tank Saturday, haven't seen him since. I have a cleaner shrimp and two blood shrimp as well. Wondering if the Harlequin shrimp is holed up someplace. Do they sleep in the open typically?

Mine used to only come out at night then when food was in short supply id see him out all the time. Im sure it varies a bit
