idenfitifaction

Darwin ocellaris clownfish I got from saltwateraquarium.com two days ago. Just noticed he has a small patch of white towards the back of his body. Could this be some type of parasite or bacterial infection?

I bought some really nice BTA from a guy breaking down his tank, I’m trying to find out what kind they are, they are a deep red like black widows but instead of white lines it’s like a fluorescent green lines and some have full green mouths as you will see in the pics

Anyone know if this is a Sherman or Black Widow anemone, 2nd and 3rd picture's tentacles should are red in person

i just got my rocks yesterday and i may have just posted about this so forgive me for being a bit frantic on the forums. can anyone identify this anemone? the picture is awful since unfortunately its in a really bad spot for me to take the photo. but its green with pointy tendrils. i thought...

@WWC I was watching a video this evening and this caught my eye multiple times but was never mentioned. Can I get a name? And is it ever fragged? Thanks! 🙏🏻 Posted pictures and video title/time stamp to help identify.

This was sold as a "rare warty sea anemone" but I can't figure out what it is. It looks most like a bounce rhodactis mushroom-- it has a "fringe" around the edge but no real tentacles, and around the center has a ring of very large, pronounced "bubbles"-- I tried to capture these in the side...

Hey all, I looked in my tank tonight and saw a large population of small snails all over everything. These pictures aren’t great but do your best. Need to know if I should be concerned or not, they almost look like baby turbo but I know that’s not very likely.

I had an aptasia in my rock and I used F-Aptasia to get rid of. Then I noticed this right next to it. It’s wavey, could be from the flow but i am not sure. What is it? My tank is about 9 months old.

Using a 200x (all I could get my hands on) I took this trying to ID algae. I can tell there is GHA, I think dinos, and what was that worm??? Thanks!

Please help me identify this crab, it came on a zoa colony

So, I had this tank for about 2 years now but 7 months ago I redid my scape with some old and new rock and within 2 weeks brown coloured hair-algae-like filaments started sprouting up. I remove them about every 3 weeks manually by hand and brush the rock. The strands feel silky and come off...

I noticed these today… are they clownfish eggs or possible algae (like bubble)

These were found in saltwater canal along the Gulf Coast in Florida. Any ideas? Thinking a type of goby.

New to reef tanks, I’ve had this leather coral frag for about a month and noticed this today coming from the bottom. It retracts like a feather duster but doesn’t have a full fan. Leather closed up tonight and got another pic of it. Friend or foe? I’ve been scouring the internet and can’t find...

Hello, ive had a pair of clownfish for about two months. Since day 1 they have been eating and acting totally normal. But today i noticed a small white spot/patch on its side. They are both still acting normal, no labored breathing or other weird behaviors. Is this something I should be worried...

I thought I had seen a few of these before I moved all my livestock from my nano to my 65g, but now seeing this on my glass this morning it very much looks like a tiger turbo snail like the ones that were in this tank before i made it into a macroalgae tank. Do I need to move it/them over to my...

Hey guys, I have a 32 gallon biocube FOWLR setup and a plant has randomly sprouted. This tank has been established for almost two years now and has never had any sort of corals or macro-algae introduced to it. The plant seems to wilt and die and then spring back up randomly. It has brown little...

Hello everyone! I had ordered this coral weeks ago but it was not in stock and they finally sent it to me, it was supposed to be green star polyps. Briareum sp, to be exact. The polyps do look like it but the shape of the "frag" is weird, its like a bunch of branches instead of a plug w a gsp...

Hi everyone, I just recently moved a 60 gallon SW tank from someone who couldn’t take care of it anymore and was curious if anyone could help me ID these soft coral species. I’ve been taking care of a few reef tanks for about a year, but this is the first reef tank that I’ve owned myself. Thanks!

There is 1000’s of these tiny white snails in my aquarium an i have a few questions about them. • What eats them ? • Is it me that has too remove them ? • Good clean up crew ? • anything i need too worry about ? • are they worth anything ?

Received an acro and I don’t know the name. Attached a photo, thanks!

So i have this algae that appears slimy on my rocks and kind of comes off in sheets. I was worried it was dinos but doesn't look like that. Under the microscope I see this: Can someone confirm whether or not this is some form of filamentous green hair algae? Just seems super small to be that

Hi everyone, I wanted to reach out again because I noticed something on the glass of my tank this morning and I believe I also saw one on the Roch this morning also. I will attach a picture of what looks like some sort of worm if anybody can help me identify this and let me know if it is harmful...

Hey reefers! Hope this is the correct place to post these photos for ID. I'm approaching 2 months since starting my first Nano 24G Lagoon so I'm still learning every day. LFS told me the names of the Zoas but didn't quite match the photo descriptions I found online. Photo 1: Looks like 'God of...

Hi fellow reefers, i have a few of these guys. They look like Cirratulidae (dont know the common english name, in germany they are called „Spaghettiwurm“). Normally they are red/orange, but mine are black? Would be glad if someone could help me identify these guys, and if i should remove them...
