hitchhicker

So i have my tank running for almost 2.5 years now and i have never seen this one before! Shined my cell's light at night, saw this (snail? Hopefully) about 4.5-5.5 inches long on the backwall...! Any idea what this one is? Not even sure where it was hiding all this time!

I just got this amazing blasto for 20$! It’s a small colony and it has what I think is a small clam attached. It’s alive still. Can anyone tell me what this is for sure and if it will hurt anything?

Hi all, First time today, I noticed these creatures around the food during feeding. It scared the hell out of my clownfish. Are these pods or something bad? Thank you

Hi All, I was walking past my tank earlier as the lights were fading out and noticed this little guy on the sand. Never seen him before. I stopped to investigate and noticed hundreds of them in the rock crevices, hiding. They kind if maybe look like amphipods or some other micro-crustacean but...

The Odd creature ever ;Doctor ;Doctor ;Muted ;Doctor ;Doctor Found this one on corals I bought from LFS. 1st I saw it on one Gorgonian Sea FAN and it was really strange, because the string coming out of there was over 30cm long. The issue I can have I don't DIP that particular Gorgonian...

This was burrowed into a coral I picked up today. Does anyone have an idea what it is? Coral rx did nothing for it.

Today I was seeding my refugium with copepods/phyto and macro algae and noticed these white balls in my sump in the refugium section as well as on my UV filter sponge. For the record these were noticed prior to adding todays macroalgae; however, I have in the past directly added LFS macro (I...

They only grow in my rainbow stylo colony and I am not sure waht they are. They have a small soft tube with what looks like two little antennae sticking out you can see 2 pairs of those in the second picture on the top of the coral.

Please help with some advice! I have no clue what this is at all. It’s about 2 inches long at least. Has anyone dealt with this before? If so please help with some advice!! Very much appreciated!!! Thank you

Found this weird white growth? Worm? On my frogspawn. Honestly not sure what it is. Attaching some pics. Any ideas?

Hello! Kinda new with the hobby and I’ve found these “Bubble” like things in my tank! Any idea what they might be??

I’m thinking it might be a slug or some sort??

I've just seen this, I dont have a clue what it is but the only way I can describe it, it looks like a snail without a shell,, is this bad or good.. The tank has only been running for approximately 2mths..

Hey y'all! So I just discovered a new hitchhiker in my reef community tank. This hitchhiker resides in a live rock I've had since mid-February of this year (2 mths). I am having a hard time identifying it. I have included a video I took today...

Can someone help me out. I picked up a zoa rock today and during the freshwater dip I noticed a small light blue shimp looking creature fell off as well as a bunch of debris.

Please help!!! My boyfriend and I have just spotted these tiny tiny white spots in our tank! They kinda look like worms? THEY. ARE. EVERYWHERE. Can anybody try and identify these things?? *the picture isn’t the best quality, i apologize for that * Also, excuse the algae! *any tips on...

Just noticed this on a snail making a trip across the front glass... Had a quick check around the forum + Google. Something common, good/bad? Photo color is an accurate representation.

Hello, I spotted something growing in my tank a roughly a week ago and didn't really think much of it. And today I noticed it has slightly increased in size (it's now ~0.5cm). It looks like it could be an anemone maybe. It's clear/pale brown with some fluro yellow/green balls on the tips of the...

Hi all, I just noticed this guy floating around in my water column twitching like crazy (sort of like a fish). Finally caught him when he was caught on a vermatid snail net lol. It looks like some sort of larvae, any idea what this may be? Thanks in advance!

I just noticed these feathery like growths sprouting from the crevices of its shell and was wondering what you guys think of this?

I believe its an isopod. Cant tell if its a good thing or bad.

So I just notice about 5 or 6 of these have popped up around my tank. I’m not sure what it is but they may have hitched a ride on my clean up crew. Any ideas what it is? It’s about the size of a pee and kind of reddish with clear tentacles with green tips kinda

I passed by my tank when the lights were off and noticed these worm like things on the glass. I removed from what I can see but sure there’s plenty more. I do not know what they are or if they are harmful to my coral any information would be greatly appreciated. Thanks

Can you help me identify this random thing growing in an old shell? I have leathers, zoas, and hammers but this guy doesn't look familiar.

So came downstairs to my office where my reef tank is. Started the morning ritual of cleaning the glass with a coffee in one hand when I saw this little guy on the glass! So excited, I assume totally safe in a reef system? Anything I can do to help it out?
