hitch hikers

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've started seeing these random white tubes along my sandbed and rockwork. Any ideas on what they might be? A worm? I'm really not sure.

I bought a few Snails today and noticed one of them has white spots on it... I’ll attach a image below, any clue what this is?

Woke up this morning and saw these white curls in the middle of my scoly. Anyone know what they are? Ill obviously dip it in coral rx and RO water, i just would like to know what I'm dealing with if i see it again.

So I hadn't noticed this before, but tonight saw these white almost rings coming off my frogspawn. Not sure but they look like worms. Is this something I need to worry about?

Recently discovered these black critters crawling in my tank. At first I only noticed a few, but tonight I decided to check on my tank hours after lights out and noticed a lot of them crawling all over the rocks and on some coral as well. It’s hard to take a picture so I attached a video link...

I just bought a new torch coral frag from my LFS that was open and beautiful when purchased. Whenever I got it home and it was closed up, I noticed something hard and dark growing from the skeleton of the coral. The coral is currently in coral dip and I didn’t think to grab a picture before I...

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

Anyone help ID that these are vermetid snails underneath my new ricordea? Just notice it tonight.

Hello, I'm new to reefing and just set up my first tank ~ 4 months ago. I've noticed an uninvited guest(s) peeking out from underneath my chalice that has grown in both size and number over the past few weeks and was hoping someone could identify them to see if it's benign or something I need...

Found on live Tampa Bay rock. Anyone know what it is?

Hi All, I’ve had a euphyllia for a while, it’s been healthy and not shown any negative signs until recently. A couple of it’s branches aren’t extended as they used to. Now I’ve noticed a load of red hitchhikers on it. Anyone know what these are and can help me decide if the euphyllia needs to...

Hi R2R, First post here and new to the hobby, and I already love the community. Over the past 5 days I've started my own BioCube 16 gal, with liverock from my LFS. At first I did happen to notice a tiny asterina starfish, but it quickly died or disappeared. Fast-forward to today, there's a...

Some info: brand new reef tank. 13g. In day 3 of cycling. Saw this guy on my rock when I came home and turned on the lights. Video attached. Thanks guys!

I have a mysterious orange growth that looks like spaghetti noodles growing on my Chateo.. I removed it once a few weeks ago and now it has appeared again, I am struggling to find any information on this. TIA to anyone who can identify!

Never seen this thing. Should I remove it?

Fairly new tank. I just bought my first corals and I used a coral dip before putting them in my tank. It removed most hitchhikers (I think) but there a few large ones that I can see and I am wondering if anyone can identify them and let me know if I should keep them or remove them. One of them...

Hello everyone, I just noticed this thing when i was looking around at night. It reacted super quickly to the light and i thought it "popped" as it just disappeared to a tiny hole in the rock... Had to point my camera on video and finally it emerged again.. hopefully those video screenshots...

Would love some guidance on what these are on my live rock. If you need better pictures or different angles let me know and will try my best. Picture #1 Picture#2 Picture#3 Picture#4 Picture#5 Picture#6 Picture#7

This just came in with Gulf Live Rock - please let me know if this is a good or bad hitch hiker

Hello guys Got a new creature on my live rock that seems to be a filter feeder... not sure where it came from or if it's bad... any help is appreciated! Thanks

I know, I know...it's all on me. I trusted a 'trusted vendor' and threw in some coral frags that looked good. And now I can confirm there has been a breach. Multiple of this little dude (as best I can tell) running around on LPS especially. Not my pic but closest I could find quickly on the...

Hi Everyone! I've had these zoas for a couple years and they started melting after a small purple/red polyp started appearing a few months ago. I now have this big transparent purple/red polyp with what appears to be a mouth, plus 3 others growing behind it. Any idea what could have attached...
