okay, what type of bug did I get with my order?
 

Noticed a few of these in the bag with the frags. Very small disk or saucer shaped, they do move and rather fast, by sort of folding their body but have what looks like cillia or flagella on the underside.

Not sure if they're from zoos are acros, (frags moved to one bag for a quick transfer)

Picture doesn't really show detail but more for size (there's two together here)

They do look like amphipod. You can see better picture in this link to compare

cant really tell but you might want to check out montipora eating nudibranch. Bad news if it is

they are more like a pill or sow bug or even a chiton.

montipora eating nudibranches or the acro eating flat worms, do they swim?

no they dont swim. They wont leave the rock. And they dont move fast, they are super slow.

looks like amphipods to me. The "cilia" are called swimmerettes (sp?) I believe.

Looks like an amphipod to me too but maybe this will help?

Great link.

Leaning towards a Harpacticoid copepod (third row down) and hoping not a Isopod (Sphaeromatidae)

bug id.
 

Looks like a harmless cope/amphipod to me. At least I hope so, I have hundreds of them after lights out!
Man, I thought I was the only one who knew what a Pill/Sow bug was.

isopods are very active and fast swimmers
