hitch hicker id

I ordered some live rock and sand from TBS and this guy came in with it. I have it isolated in my frag tank currently while I try to figure out exactly what kind of snail this may be. Any ideas?

I would appreciate anyone helping ID this hitchhiker. My tank is currently unstocked and about 3 weeks old with live rock.

Can anyone help me ID this snail? Thank you.

Can anyone identify what these little critters are that were hiding in my filter media? Assuming a species of nudibranch? I had put two berghias in the tank months ago to try and get on top of an aiptasia infestation, but haven’t seen them since and am losing hope. These guys don’t look like the...

Hello all, I upgraded my tank some 10 months ago and went with new, live, rock. I went with a combo of Marco Rocks Mauricultured and Tampa Bay Saltwater live rock (So all from the Florida keys), and I've been struggling (failing) with almost any form of SPS since. I spotted these three snails...

Hi guys, I haven’t posted in a long time. I need some help. I’m trying to figure out if this is a Majano anemone or a rock flower. I found it the other day on my bubble corals skeleton that I just purchased a few days ago. It’s about the size of a pea for reference.

Found this moving across the back of my tank. I know it's a snail, but unsure which one. May have came on one of my new nassarius snails. Any ideas?

I was turning off the lights in my aquarium when I spotted this white worm swimming in an S shape around my tank. I removed it because I have no clue what it is. I've seen bristle worms before but i've never seen them swim and i've never seen them in white. the worm's about 1 cm long. I've...

Found about five of these tiny, wispy hitchhikers on live rock I bought from Gulf Live Rock. I’ve read that the gulf doesn’t have the invasive aiptasia. Is that true? Has anyone kept these and they not spread? If it is aiptasia, what is the best way to get rid of it? The rock is in a quarantine...

Any idea what this is and if it’s going to be a problem? A few came in on a coral frag.

caught one of the two i saw in my aquarium, should i start hunting for the other one

Any Ideas? Some kind of clam or barnacle? It seems to extend a little bit at night but i can’t see feeding tentacles.

It's a nano tank that's still cycling with live rock from TBS (I think, I bought the tank, rock, and macro algae as a kit?). It's been rough going since I knew absolutely nothing about marine aquariums when I got it but parameters seem to be stabilizing, albeit slowly, and now I have a bit of...

I dont know if this is a worm or a spider star fish. I have not bought any star fish nor have I added anything to the tank in a very long time! I assumed they are worms but I dont know what type and if they are good or bad

I need help identifying this worm lookin thing. this is the first one of it's colouration and size i've found since i got my live rock over a month ago. based on the fact that i can see bristles on it, I'm assuming it's a type of bristle worm and not a planaria. my issue is trying to figure out...

Found these in my tank while looking at it with a flash light , very small so it was hard to get a picture but if anyone would be able to tell me what they are or what they could be I’d appreciate it. I added what video and pictures I could take after catching two in sample cup

Hi all, Does anyone know what this could be? It’s spreading quite aggressively and seems to irritate my corals. I’ve looked around but haven’t found an identical ID yet – to me it resembles colonial hydroids or possibly majano anemones, though I’m not certain. Thanks in advance for your help!

noticed this lobo coralhas been having some issues notice some white buildup on the side look like worms. Took the coral out and decided to dip it today in a revive and iodine dip. Then I noticed these white worms looking things were coming out like crazy. Was wondering if anyone had any more...

Can anyone ID these? They’re randomly scattered around my rock. They don’t have an obvious shell like vermetid snails. They literally just come out from the rock.I’ve also had vermetid snails in a prior tank and these are different. I’m expecting a similar filter feeder with a stringy/fuzzy...

Came home to dozens of these on my refugium glass.

I am relatively new to reefkeeping, and I'm trying to identify this worm. I thought it was a normal detritus worm at first, but the antennae are making me think otherwise. Thank you for any help!

Can anyone ID this thing on the glass? Is it a Copepod? Up close it kind of looks like a pill bug & it swims around the tank upside down, going to different areas of the glass… I’ve been seeing it for around 3 days now - it doesn’t hide in the rocks at all. Any help or opinions would be...

Does anyone know what this could be, the hammer head has been dead for a while I recently noticed this growing around the edge of the head now starting to grow inside the polyp almost looks like an alveopora or is the hammer regrowing?
