hitchhiker

I found a nice piece of live rock with some copper banded coral on it. The guy at the store thought it was some rare sponge with an N name but he couldn't remember.

All of my zoanthid frags starting disappearing over night and I noticed these snails a few days before I noticed my zoas gone. If anyone can ID them for me that would be much appreciated. Need to know if I need to completely wipe them out or not. Has anyone else had their zoas disappear within...

I woke up at about 2 am to enjoy my tank when the lights go off and there are hundreds of baby snails on the rocks and on the glass.. I also saw what looked like a baby urchin and some type of starfish. Can anyone help ID them?? I posted some pics. They’re not the best because they’re at night.

So yesterday I saw a Mantis Shrimp (I am assuming it was a mantis shrimp) pop out of the rocks. He must have been there for quite sometime as I haven't added in anything new for a while now. This would explain the mystery of my missing invertebrates (a few months ago my cleaner shrimp both...

Discovered this a couple weeks ago and been monitoring it. It was initially in the crevice of another rock for a few days, but moved to this area a few weeks ago and has been here ever since. Seems to be active during the day, and hides at night. The "arms" move away when touched by another tank...

Still as yet Unidentified purple live rock hitchhiker is translucent, reactive to light and danger from other creatures, will turn almost solid white when withdrawn near the entrance to its hole in the rock.

These guys have been in my tank for quite a while, kept meaning to get an ID and today finally getting around to it. Any idea what they can be? they are smooth, but not squishy. You can see them in the first part of the video on the rocks. Tank is about 7 weeks old in total now.

I was on the prowl for red macro algae and didn't ever notice this guy stuck to one of the pieces. Only when I put the pieces into the tank it felt squishy and I noticed something on it. Is it some kind of sponge? it can shrink down surprisingly small when it is touched, vents open and close...

Any advice would be appreciated? I can't seem to find any info about these guys online... Loads of them hiding in the rocks, purple-ish tentacles everywhere. And found this 7-legged critter also! They don't seem to be a problem?

I am almost positive it is a worm, it has a white head, and redish orange to yellow body. it darts around my tank like a mad man..it wiggles and darts.. it is about 1/2 inch long. in the video it looks all white. I am trying to get my daughter to video it in the solo cup she caught it in...

Can someone please tell me what this coral is, got it from a lfs. Also there’s these tentacle hitchhikers on the side of it. Should I try removing them? Are they harmful?

Hi all, This white mossy mass has slowly grown on my Duncan frag. Recently it has developed these cylindrical growths with little branches on it; there are a handful of those. In the attached picture I have circled the entire mass and am pointing to one of the growths. The closest ID I could...

I noticed recently that two frags of the exact same acropora were healthy one day, then completely white a few days later. I checked parameters and everything was stable. Al the other frags are fine. Then two days later another millepora in the same section of the frag tank experienced the same...

I found this small orange snail in my tank this morning. He would have originated from some live rock that was acquired through gulf reef live rock. Thanks as always for your help!

Hi Guys, I swear this is something new. Okay, maybe it's just aiptasia. I want you to see if there's something I'm missing though. I added a colony of Pink Hippos (zoas) to my tank about 2 months ago. Before adding, I dipped in Coral Rx (standard procedure). I had second thoughts about this...

Hey guys so i noticed one of my hermits has something growing on his side inside his shell it usually hides but i got it to come this took some pictures i was thinking it’s some type of feather duster maybe? If so i kind want to keep it how to extract it lol or will it come out on its own

What is this? I found it stuck to the tank glass a few minutes ago...

Yesterday I added a new feather duster to my tank. This evening I spotted this on the rock near where the feather duster casing sits. Is this the feather duster? I'm a bit worried that my sexy shrimp are interested in it. I've had mixed results with these guys - some I've had for a year (still...

Anybody able to id this bivalve?

Need ID please He was in the coral base that I was dipping into Coral RX, promptly died after but was wondering what type of snail it was. Sorry for the picture quality it was hard to get a good picture. It had a red shell with spots. Reminded me of a lady bug

Long white stringy creature living in chaeto. It retracts when I touch the water or it senses vibrations on aquaclear filter. Maybe some kind of worm??

Hello everyone, I am having trouble with getting a positive identification on what appears to be an Isopod of some sort. This is the second time they have appeared in the water column since I have upgraded aquarium sizes and added live sand. They resemble Cirolanid Isopods, but they are very...

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
