hitchhiker

Dear reefers, I got this green star polyp 1 month ago and now notice there's a possible aptasia? Anyone can verify? thanks! Attached video below taken during light off with ambient room light, polyps all closed up.

Hey all found this in my tank last night and forgot to post it any one have any ideas?

Does anyone know what this yellow is? There’s also a wired mussel looking thing lol

Hello All, Today I took out macro algae to clean and rinse and found these guys underneath the branches. they aren't moving actively and seem attached permanently to my macro. when trying to detach, they break and "head like" part stays on macro. Either it has mouth attached to macro or it...

Hi all, I’ve had a rose BTA for nearly 3 months which came attached to a small piece of live rock. Today I noticed what looks like two aiptasia growing on the rock. I’ve had these come in on some coral frags before which I dealt with by smothering in superglue, however those were white and...

Hello! I've got a strange hitchhiker on a zoa rock I got. Noticed it this morning when I was feeding my corals some reefroids. https://photos.app.goo.gl/nzfTw5MGDEtZ4vP5A It looks like some sort of filter feeding worm, but I'm curious which type. Apologies for the poor quality video, but it's...

Can anyone ID this?

Hey guys! Any ideas what this could be attached to my little snail? Good guy? Bad guy? How to remove if bad? Thanks! Tank contains: 5 snails, 2 occy clowns and a blenny

There is no triangle head...

Ive only just noticed it today, the tank is only a couple months old. Please help identify, after browsing the web i still haven’t found anything like it haha, It’s only around an inch big and it looks like it has pores

Anyone know what this hitchhiker is? It came in on a frag from a recent live sale. It looks like a small aquatic version of a roly poly. It has a bunch of legs (10 at least?) and two very small distinguishable eyes.

I recently got in some live rock from the gulf and was wondering if anybody could tell me what kind the two are.

I purchased this blasto during World Wide Coral's anniversary sale two weeks ago. After one week I noticed a red egg / growth appear on the base of the coral. The egg / growth in question is round, large enough to stick out from the base of the coral slightly, and has a small white thing...

I noticed a bunch of these weird things growing on my soft coral, is it bad? And what is it please

I bought my first ever coral about 4 months ago, a small 2 head Torch and a fungia plate coral, I dipped them both and got a small flatworm off the torch luckily. A few days into owning the torch and watching it get used to the water and extend, I noticed a little section of bristly exoskeleton...

My 4-month-old tank has been thru various phases of the uglies that have been relatively mild, but I see a new growth that I'm having a hard time identifying. As shown in the photo, these white fuzzy stalks are attached to rocks (or the back wall) -- the one pictured is about 3 mm tall, others...

We all like to treat our Coral with dip and maybe some of us don't do it or never have at all. I would like to know, what is the coolest hitchhiker that has made their way into your tank? Through buying Coral, live rock or live sand or anything. It would be interesting to find out if anyone has...

Hello, anyone know what kind of cowrie this is? Thanks in advance.

Hey everyone so i just noticed this guy crawl from the top of my rock work all the way to the bottom pretty fast. In thank I only have 4 corals and 2 clown fish and 3 bubble bee snails in a 13 gallon. Started the tank in January and put coral in march 1st and fish march 29th. This is the first...

Hi everyone, I just finished dipping and acclimating my new corals that shipped in. A couple hours later I was admiring them as they all opened up and saw this tiny starfish hanging on for dear life as my power heads blow him about lol should I keep him? Or is it a bad hitchhiker. I don’t know...

Wish I could post a video as it would show up much more clearer and movements (possibly just water current moving it). I went through the Hitchhiker ID Thread with the various photos and the good & bad ones, but clueless. I’m just wondering if this would be something of concern or just me...

Stationary tentacle or worm, nocturnal, rapidly shrinks in bright light to what basically just looks like a pebble of sand stuck in a some snail slime. Edit: not sure the video is going to work so here are stills

This thing is growing on my snail but can’t work it out what it is. If a touch it closes like clams it doesn’t seems to bother the snail but would be nice to know it is safe.
