What animals are there?

Hello guys,

in a frag i just bought i found these little things. What are they? Some of them reminds me mosquito larvae.

Are these good, or have I brought parasites with the coral?

thanks

Skeletal shrimp! Completely harmless filter feeders, I believe. You can put them back.

I remember when I bought my first live rock and saw theses types of critters wiggling all around - killed them all... Now I don't have any and wished I'd left them. Lol

Colo thank you! What about the other animals I touch with a knife in the video?

Looks like some sort of isopod

I think those are mysis actually.

Yep, sphaeromatid isopod. Harmless.

The wiggly things over near the frag are mysis, maybe. Some sort of shrimpy-thing. I'm focusing on the weird thing that's about a third of the way from the top, the one sort of tumbling around.

Hey, italcool, could you catch the weird thing in question and get a better picture? Whatever it is, it's cool.

Too late.. I poured the whole thing in the sump..

Well, for future reference, those weird-looking things are harmless.
Also, there's probably more skeleton shrimp on the frag that are just hiding.
