THE ULTIMATE ID THREAD! Before you post WHATS THIS? LOOK HERE!

Recommended Posts

Can't get a clear enough view to positively ID it for you. However, there are thousands of types of dusters. So, it's likely that's just what they are. Perhaps it's just a goofy angle. However, the one circled on the lower right in pic 2, appears to have a tube.

Ive searched a lot but I cannot seem to finalize what these things are. They seem like feather dusters, but I cannot see them growing out of a tube, instead they seem to be growing out of rock crevices. I can be mistaken is this is my first tank, but to me they seem like something else. Also, unlike feather dusters, they seem to have short and stouty bristles instead of feathers. What are these things?

I think the one on top looks like the crown of a peanut worm.  Does it move or just suck back into the hole?  Peanut worms "unfold" a little crown and can actually sweep it around kind of like an elephant trunk.

I tried a lot but I could not get a clearer pic. Yes, one of them does appear to have a tube, but still it is unlike any feather duster I can find online.

Google results for peanut worms match this critter a lot. It doesnt seem to move much, but its entire body sucks back into the hole at times, some of them appear to have a tube like structure beneath the crown of tentacles, which moves into the hole too. It does not seem to get its body out of the hole. It is nocturnal and shining a flashlight over it makes it shrink back inside.

Had no luck I'd ing these. Does anyone know what they are? It looks like acro redbug but it's bigger and completely red, not orange with red dot aka acro redbugs.

 

they seem to appear after feeding my tank reefroids, crawl around slowly.   Then once finished disappear under corals /rocks etc. My sps look fine and growing well ,so I'm thinking they are some kind of tiny scavengers??   Tiny red dot on small blue acro.  And bright red dot in glass jar. There's quite a few when they come out all over my rockwork mainly

Any idea what this is? It certainly is green like algae. The little head on the end and the fact that is pretty stout and and not moved by the flow at all is confusing. It is about 3 mm long at this point. It is the only example I can find in my tank, currently.

Can't really see much. It's hard to focus on such small things, especially when there are rocks, and whatnot, that tend to get the camera to focus on them. So, any description to go along with the pic?

 

I could afford a few guesses, but that's all they'd be without a description, or clearer pic.

Maybe nerite eggs, maybe baby snails, maybe hydroid medusas, maybe a lot of things....

Hi,

 

I hope you all might be able to help me identify this critter that suddenly appeared in my chaeto....

The heads dont pulse, but open and close periodically and can retract when disturbed. The bottom is pretty hard.

Yeah, also have a slight flatworm population I've been trying to keep down, and a minor bubble algae problem, but the bubble algae has never bloomed, it stays small as I tend to attempt to scrub it off of easily removeable rock which is where it tends to be. Im

It’s hard to tell - colors look so different out of the water!  My gorilla grab was much lighter in color, very hairy and the tips of its claws were dark brown or black.  And I wanna day was shaped differently overall - but!  May be the difference in sexes??  Mine was horrible and I finally got him out and my corals have been thriving since!
