Just got 5 pep shrimp from a LFS, and one of them has a swelling on the side. They are still in the bag and I am getting ready to acclimate them, but I'm concerned that the swelling could be a parasite. But isn't that what an embryo is until its born? Maybe its pregnant? But from the side?

Has anyone seen this. My inclination is to quarantine it for now. Any suggestions?

I really need your advice or insight folks.

it is a parasitic isopod. nothing you can do, but it is safe to add the shrimp to your tank

It's a bopyrid isopod, parasitic as fishome25 said. The large lump is a female which may have dwarf males attached. I suggest taking it back to the store. You don't want this reproducing in your tank and infecting the other shrimp.

Well it's not pregnant, they keep eggs under the tail. Could be some endoparasite, whatever it is it's not normal. Take it back for a refund, no need to risk it.

Search on here for it. There were directions on how you can remove it. Its between 2 layers of shell and if you have a steady hand you can cut it and puti t out and it will molt its outter shell....but I would just take it back to the store! Thats what I did...they suck the life out of the ltitle guys...

There's a little more information here:

Removing the parasite will often cause more damage to the shrimp then just leaving it alone. I checked some references and you don't have to worry about your other shrimp being infected if you keep it. Turns out the bopyrid larvae first live in copepods then transfer to shrimp. Each species of bopyrid requires a certain species of copepod. It's quite likely that you don't have the right kind of copepod in your tank which means none of the juveniles (if there are any) will survive long enough to be a problem.

Thanks. I feel much better. Just to be safe I put in quarantine last night. Thanks for all of the great information. As always, very educational for me.
