cleaner shrimp dead :(

[purple tang]

Just an update to a post made a few weeks ago...

I had posted about my cleaner shrimp doing badly. Just sitting in one spot,
looking off color (at the time he/she looked like it had eggs - that
apparently was not related). I removed him from the tank and put him in a
hospital tank for about a week and half. He shed and appeared to have made
a full recovery. After putting him back in the main tank, he again stayed
in one spot and just sat there. This morning I found him being eat by the
CBS. The two had previously been in the tank together (75 gal w/ 100 lbs
LR) for over a year w/o any problems. It appears the CBS suddenly decided
he wanted to be the only shrimp in the tank. (he has gotten rather large
since he was first in the tank). I recall some posters suggesting this may
have been the case. Not sure what I could have done other than selling one
back to the fish stor. Just wanted to give an update for what its worth.

Sorry to hear....
How long after it shed did you place it back into the main tank?
They are vulnerable just after they shed...
I noticed the same behavior from a few standard Prawns/Shrimp that you catch
in the ocean to eat.
After a few months they looked like they were trying to shed and then one
morning they were fish food....
One even appeared to be trying to use the filter intake to try and help shed
himself.
Each of the 4 I had died in exactly the same way..

Hmmm. I didn't think about that when I put him back in the main tank, but
it was pretty early when he shed- probably shed in the quarantine tank no
later than day 3 and was in there I'd say at least 7 more days before he was
placed back in the main tank.

Do you know if he was eating after he shed his shell?
I am not sure how long it takes but I assume that after 7 days that his
shell would be back to almost normal.
Would have been a good idea to put him back in the main tank just after the
bigger one had shed, there would have been less chance of the larger one
attacking him.
Apparently when breeding commercially eaten Prawns/Shrimp they try to time
all the shedding to be at the same time so hardened shell Prawns/Shrimp dont
take advantage of the weaker shelled ones after they have shed.
I cant see it being much difference with all types of Prawns/Shrimp.
I think there was always going to be a problem though with one being
larger...
Once again, sorry to hear of the loss. Shrimp are facinating creatures...
I have a mated pair of CBS and they dominate the whole 55g tank. :)

These shrimp pair up, like most animals, when they are separated their bond
is broken and when put back together they don't know eachother. That might
have been the cause.

interesting. I know he was eating and moving about very well before I
placed him back in the main tank. Appreciate the input!

How exactly do they influence shedding time? High doses of iodine?

I know if you place two Lysmata shrimps (cleaner, blood or peppermint)
they always synchronize over time to shed on the opposite times, not
together... They play female/male roles on exchange with each other.
Of course, it does not apply to two shrimps when different spiecies...

I don't know how they sync the sheddings, I didn't read further into it.
I read this on a few breeding web sites for Prawn farming, They said it was
a common problem with the shedding Prawns being attacked by ones that were
not, so they somehow had them all shed at once.
I wasn't interested that much at the time so I didn't bother readiing any
further into it.
