Cleaner Shrimp : Strange Behaviour

[Captainhemo]

Hi All
I have a cleaner shrimp that molte on Friday. Saturday, he stayed in his cave all day/ night long, and wouldn' t come out at all which I understood was normal. Yesterday, when I got up and looked into the tank, he was sitting way up high in the water colum, just sittin ghere doing nothing. When the lights came on, he promptly moved to a rock, totally out in the open and pretty much stayed tere all day, only moving a small amount side to side on the same rock. He did spring into actin when I dropped in some mysis shrimp, he ate it , then went back to the same spot.
I wokr up this am , and sure enough, he is stitting in the exact same spot but appears to be way more active today. He is moovibng around alo t more and will " floolw me" to the other end of the tank but wont stay. He just goes back to the same spot.
He looks fie, no signs of trauma or anything, no visiable damage, his colr is normal, everything looks fine, he just is very inactive compared to " normal".
Water parmaiters are norm : sg. 1.024, ammonia =0 , nitrites=0, nitrates = 5.ppm PH 8.2, temp 79

Is this behaviour likely related to his recent molting, how long does it usually take before a shrimp is back to " normal" after molting ?
I'd apprecaate any thoughts or comments regarding this, I"m kinda worred about thim

Thanks
