What type of Isopod did I find?

[Woodyman]

Harmful, neutral, or beneficial?

I haven't had any coral shipments local/mailed with an Isopod like this before. Google was of little help finding someone I would call a positive ID.

I found a total of 3, all came off when shaking the frags in the shipping water.

No additional ones found when dipping.

This is under a magnification of 0.7x

Possibly the same as here?

Isopod ID

Any ID on this isopod that came off during a dip? It didn't curl when dying and I had read the good isopods "Roly Polly" . This thing was larger than a small astarina that came off as well.

I’ve only studied so many marine isopods but I am wondering if it is Family Sphaeromatidae. Paracerceis sculpta. A type of exotic marine isopod. I am uncertain if they are considered reef safe.

where did it come from? which vendor?

 

[taricha]

that body shape is shared by types that hang on to fish as parasites. I'd presume bad.

 

[Woodyman]

For now they are isolated in a 15ml falcon tube hanging out. I'm assuming bad as well.

Not from a vendor on the site it was a small store I stopped at.

Do they curl up into a Rolypoly shape when poked? If so, probably a Sphaeromatid. Also looks like the eyes are on the side.

Looks like a Sphaeromatid, so it's harmless.

At least it's not one of thesehttps://youtu.be/O8sE0tvkpdY

They did not curl

Looks like a parasitical isopod that will be a problem child

Need to see the eyes.

Good:

Bad:
