Sick Cleaner Shrimp

Hi everyone,
The thanks in advance for your help. I just bought a cleaner shrimp for my 10 gallon aquarium on Tuesday. I wasn't sure if he was eating so I hand fed him on Thursday morning(flake food) and on Thursday night(flake food). On Friday, yesterday, morning I tried to feed him some brine shrimp and he wouldn't take it. Same thing in the evening. This morning he is acting like he is weak. Just sorta laying on the sand. On odd thing is there is something white on one of his front...legs? I'm not sure what the correct term is. Anyway he tries to get it off and then sorta sits down to rest. I usually do a 10-20% water change every Saturday. PH is 8.0, Nitrite is .3mg/l, carbonate hardness is 14, ammonia is 0mg/l, SG is 1.024-1.025. I expect some of those figures to change as I am doing a water change. Can anyone suggest some things I might try or tell me what I'm doing wrong?! Thanks again!

 

I have had a pair of cleaners, for about 1yr now. Haven't had any problems. :/ Try feeding it Hakari algae wafers. They also lie the seaweed I have for my coral beauty.

A picture would help too.

 

Thank you for the suggestions. I tried to get a picture up but it said that the picture exceeded file size or something like that. The only thing I have to take digital pictures with is my phone and they are hard to make out anyway. I might be able to get my hands on a digital camera later tonight or tomorrow. I hope its not too late by then. This little guy really doesn't feel good. I wish there was something I could do.
