hitchhiker coral

Hi! Does anyone know what these are? Friend or foe? They've started popping up all over 2 pieces of live rock that came from someone's tank breakdown. They appear to be attached and aren't moving around. The fan looking end doesn't retract or spook like a feather duster worm. The fan looking end...

What that heck is on my urchin?? He has been carrying it around for almost a week and it has not moved. Its fluorescent and only appears yellow under blue light.

I was taking a couple pics of an anemone and noticed something behind it that looks to be some type of encrusting Lps hard to say with how small it is. Any ideas?

Hello, this is the first time buying coral online and I want to know if these are hitchhikers. If they are how do I get rid of them without damaging the coral.

Found this coral growing on the back of a snail’s shell. Store had it labeled as “ninja star astrea snail”. Quick search resulted in nothing about them being captive bred, and since they’re native to the Atlantic. This leads me to believe the coral is some sort of Atlantic sps. Can anyone chime...

Can anyone identify what this is growing on my rock? TYIA

Noticed these weird purple growths on my zoa and duncan frag plugs. Can anyone tell me what this is?

I am brand new to salt water aquariums. We got some live rocks from a local store shortly after setting them up in our brand new tank I noticed this on one of the rocks. I’m wondering if it is an aiptasia. We also have a few brittle starfish that have come with the rocks. And if it is any advice...

Hi, you Guys know What coral this is? I think its a blasto merletti, i have it for about 8 months has not got any more heads. Bit had grown in Size. Has not spread anywhere either. Thanks. Hiker

Hey everyone , thanks for your time I saw this this morning and I wanted some clarification about what animal that would be. Thanks

I'm looking for an ID on these little purple buds that appeared on my zoa frag. They survived a coral dip when I first got them, so I wasn't too concerned about them until I found more elsewhere in the tank. I'm thinking they're some sort of clove polyp as I think they have multiple arms, but...

I got these Fuzzy white polyp-like inverts that has started to grow on my reef rock They kinda look like hydroids or miniture soft corals Just want to comfirm if they may be anything bad or i should just leave it

Some clove polyps hitchhiked into my tank somehow. They are isolated to a small are about the size of a half dollar on a movable top rock. I have contulinously removed them by removing the rock and brushing them off with a toothbrush destroying the polyps under running water. I don’t do this in...

Just noticed some little additions that I hadn’t seen before. Does anyone know what my little hitchhikers are and if they are dangerous? Thought maybe Asterina, not sure what the others are near my mushrooms thanks in advance for any help!

Diploria Labyrinthiformis, aka grooved brain coral, is one of my absolute favorite corals! Seeing it while diving always puts a smile on my face. I’m setting up a reef tank and if I could have this in my tank, it would absolutely put a smile on my face every day. now to cover the most obvious...

Hello, i just noticed this thing growing on the side of my frogspawn coral. It's soft and the striped mouths close when poked at. After some research, I think it might be a sea squirt but I've never seen one that looks like this so I was hoping someone else could help me identify it. Is it...

Somethings been growing in between and on the plug of my zoa for sometime now, i did a hydrogen dip two weeks ago and that barely seemed to help. Then a coral dip this week and nothing as well. Its almost translucent and looks like very mini tentacles, however it doesn't seem to move. Its grown...

Recently bought this guy at a show and it’s in my q tank atm I’m not exactly sure what it is growing on them but the guy was not very forth coming so obviously was a poor choice I just haven’t been able to find out what it is thanks in advance I also can’t tell if it’s aptasia or not cause it...
