What is the growth on peppermint shrimp

[bigroost]

Got in 6 peppermint shrimp this morning, 5 were fine, 1 DOA. What is this growth on its side? Should I be doing anything for the other 5 in QT?

Looks like osmotic shock. Change in it's water SG (usually lowered to fast) causes their guts to come out. Kills them.

Why this happened to this one and not the others, mystery. But could have happened before shipping.

I wish I'd messed with it a bit. It looked solid like there was shell around it.

Might be an isopod. Typically, the kind that affect cleaner shrimp aren’t a big deal. They don't usually kill the shrimp and can’t multiply because one of the stages requires very still/stagnant water, which isn’t common in a reef tank. I had an isopod on a cleaner and was all worried until I did some research and found that there was nothing much to worry about.

Do you still have it? I second a parasite... I have seen them come in on a few of my collected species.

It eventually fell off/disappeared.
