Cleaner Shrimp Woes!

[BearLee]

My little cleaner shrimp has had waves and curves in his antennas that he has never had. I'm at a lose for what could be causing this. My water tests the same stable parameters it's had for nearly a year now. I do weekly water changes and try very hard to keep everything stable and stress free.

They normally do not look like this. I also can see one is broke off too.
That has happened within the past few days.

This is how he normally looks.

Any help from this awesome community would be greatly appreciated. I've had this little guy since Christmas of last year. I am worried about him. His name is Barkley.
(As in Regg Barkley on StarTrek TNG)
((Yes, we have a Star Trek naming scheme.))

He may have just finished a Molting stage. You should dose some Iodine as it helps in their Molting.

Bet he got them caught up in the powerhead? ouch!

Yes, most likely a result of a recent molt, it should straighten out with the next molt. Routine water changes should provide the necessary trace element replacement.

Thanks for the replies folks.
I'm doing my first water change with the new salt mix tomorrow. I got the H.W. Reefers and am going to give it a go.

I had been using Red Sea(Coral Pro) and was not happy about how sticky it felt, so when I ran out, and my preferred LFS was out as well, I gave Fritz(reefers) a try. I tested it and the batches were always low on calcium, alk., and mag, so I was having to buffer those. I had not considered that the iodine might be low as well. (D'oh!)
I'm about to run a test on that and see if the level is off.

The peppermint shrimp, Rō,(as in Ensign Rō) is looking totally normal and I know she molted last week.

I haven't seen Barkley's carapace in the tank, so if he molted, someone ate it. Lol
