I have seen these strange things in my tank for a few weeks now, they look sort of like little white orbs connected on top of transparent stalks or tentacles of some sort, at first I thought they might be eggs or even some sort of anemone. I've had Aiptasia before and these seem completely different. I'll attach a few pictures even though the quality is pretty bad, has anyone seen something like this before?

These little anemone looking things with white dots at the center and little fingers around it popped up all over my new live rock on the coralline algae. Anyone got an id? I can’t find anything online.

Ok guys and gals, I bought this nice coral skeleton off ebay and as far as I know of its in the acropora family but i'd like to know exactly it's full scientific name. Any help would be Very much appreciated!

My tank is fourteen days old, this morning I saw the glass was covered with these little tufts of brownish or greenish "hairs" for lack of a better word. What could these be? I assume some sort of algae but they don't look like the diatoms in my tank, any way it could be the beginnings of GHA?

couple pics below. The darker tan pics from the top of my tank have been there a while and slowly grown to size over about 4 months? The other tiny single polyps? On the rock I just noticed today. Perhaps half a dozen to a dozen of them in sprinkled in a couple regions of tank.

I got this new frag from a local reefer. Not sure what it’s called. I’d love to know if any one has any ideas

Hello everyone looking for s little help. I can't figure this one out but I'm guessing eggs? Who's the culprit? Various snails-about a dozen total. Three variety of hermit crabs. A fire shrimp. Two clowns. A clown goby and a green chromis. So it's gotta be snails crabs or clowns right? It's in the top corner of my tank where the coralline doesn't grow. Just beneath the power head. Fluval 13.5. About a year old. Thanks!

Came in on live rock. Very rigid blades with a distinct rib around the margin. Any idea on species and care? Thanks!

Hi guys, I have 2 month old Fluval Evo with live rock, live sand, CUC and a couple of clowns (literally and metaphorically). I was taking a look at the tank this morning and spotted something I hadn't seen before. It appears to be in a tiny white spiral like shell or body with a red 'head' protruding with lots of small appendages. When any of the crabs come near it he will retract then emerge again a minute later. The head almost looks a little feather duster like to me but he appears to be rooted to the live rock. I've added a couple of pictures, one retracted and another when he's out. I apologize for the poor quality of the 'out' picture but it's pretty far back in the tank and this thing is tiny (Biro tip sized) Any help will be greatly appreciated.

Hi guys, I recently setup a Fluval EVO 13 gallon nano reef. It contains live sand and live rock and finished cycling about 3 weeks ago. Following the cycle I stocked the tank with a small Emerald crab, 4 small Hermits and 3 medium size turbos. There are a large number of Spaghetti worms in the rock but tonight I spotted something different. In the picture you can see about 6 small tentacles in the dark area of the rock, the nearby Hermit is about the size of a thumb nail for comparison. The tentacles move but very slowly as opposed to the Spaghetti worms which are significantly longer and much more active. Any ideas? Thanks

Hello everyone, I was hoping someone could help me ID this coral,I saw it up at my LFS for just 15 dollars a frag and I figured why not,the guys that work there said they weren’t sure what it was. It’s definitely some kind of encrusting coral,if anyone has an ID on this I would appreciate it,thank you!

Found hiding in a coral covered rock, LFS has no ID on it. Color is a deep red and green strip/splotches. Definitely a blenny of some kind.

So I wen to a local LFS and noticed they had 2 wrasse. Both labeled as "flasher/ fairy wrasse". Now I can tell one is for sure not either a flasher or a fairy but appears to be closer to a Halichoeres Sp., but the other looks like a fairy but I couldn't ID it. Anyone know, or have a suggestion to what they could be?

Hello guys... first post since getting back into hobby after a few years... says I joined in 2009 haha. Anyway, any idea on what is growing on my rock? It’s dark brown/maroon and looks like a dark Favia Coral. The zoomed in picture is the closest I could get. There are a few spots elsewhere like this too. It’s not as spotty as the coralline algae I had in the past. Tank is two months old and only has cuc inhabitants. Running chemipure blue nano, filter floss and the heater and pump in the back. Besides the wave maker, no other equipment or dosing. Not sure if any of that matters.

Wanted to know the name and type of this frag

Hi guys looking to possibly ID the owner of this egg sack. We found 4 total mostly attached to clove polyps. Have you ever come across eggs shaped like this? Thanks!

Good morning Reefers! Â Can anyone tell me what type of algae is growing on what I think is my Pink Branching Cyphastera? How could I remove it if needed? Thanks in advance!!

Hello, I bought this frag and I donÂ’t know what it is. The guy at the pet shop told me twice but his accent was strong and it sounded like he said apec but when I got home and typed it up I couldnÂ’t find anything. Thanks in advance!Â

Can anyone help ID this crab? Found it living in maidens hair i got from live aquaria.. It has been in my tank for a while and didnt even know it was there until i saw it poking out tonight..

I saw this teeny guy on one of my snails this morning. I have also seen them before on my LR. I've never seen them move, but if I use my turkey baster and blast them with water they close up like a coral. Any ideas for me to look into would be greatly appreciated. I got nowhere looking through all the usual pests

So first corals and first tank. I have been watching a tube like thing growing out of my Candy Cane. I was initially very excited thinking it was new growth. It isn't is it. Possible spionid snail? Or different color vermitid? Friend or foe. I also noticed a discoloration near the tube thing on coral head. It is also circled. Ideas?

I just picked this up today a small frag. Unfortunately I don't remember what the guy at the lfs told me it was. Any help would be greatly appreciated.

Need some help here! Just started up a 20gal nano and tossed in 10lb of GulfLiveRock. A week later and I have these little guys crawling around during the day/night. they seem to go wherever just munching along! Edit: they are really small. maybe half the size of a grain of rice Thanks a bunch!

Kinda sucks this is my first post on a forum I lurk almost daily on. but anyways, I noticed with my first 2 corals I have bought (a pulsing xenia & GSP) that one is doing great and the other looks like it's been receding. My xenia is growing and doing really nice so I wont talk about that one, but instead on my GSP. I know that you have to give a coral some time to acclimate to the tank and leave it alone. and afaik sometimes with GSP it can look pretty bad before bouncing back. well I decided to look at it more closely and i saw this white flatworm move in some of the crevices. I decided a freshwater dip would be best for about a minute, but besides the amphipods it didnt want to come off, I manually used my aquascaping tongs to reach into the coral and pull the flatworm out. well after putting the coral back into the tank, i must have agitated the flatworms, because i have pulled another two off the coral. tank specs to best of my knowledge size: 10g 2.5 months old 1.025 ppt salinity 0 ppm ammonia 0 ppm nitrite 0 ppm nitrate ~180 ppm kh 2 20" stingray LED on timer chaeto refugium AC 20 sponge filter 1 occ clown & TSB 3 electric blue hermits 1 trocus snail ~ the question is, can I have an ID on this flatworm? I searched online and this forum but cannot find anything that looks like it. And if anyone knows what it is can they tell me if they are beneficial or parasitic? could this be the reason my GSP is not doing well? Thanks ahead of time for the replies,
