identification

Never seen or heard of this issue before. My Red Sea gravity ATO basin just spawned all these weird squiggly worms. See video The new action I did - which shouldn’t make a difference - was use a measuring cup laced with vodka to gather water for my carbon dosing recipe. Any ideas on what...

Got this macro from my LFS but never asked about the name, any ideas?

My the place I live does a "city wide clean up" where people throw whatever to the curb and then a truck comes and takes it. This provides numerous opportunities to find unique things that people just toss. TVs, cabinets, instruments, and in my case a fish tank. My problem is I have no idea...

Found this guy in a lfs. Looks like a ton of baby lps heads but apparently it was encrusting a rock. The person working told me it could be a goniopora but I would like to know what you all think.

Hey everyone, my aquarium is about 1 year old, this thing growing on the glass since the last month or so. it would be great help if you could help me ID it. in the video in the last 20 sec, it is a bit blurry sorry, It is shot with a magnifying glass since it is so tiny. thanks

Hi R2R Team, I've been battling a nuisance algae for a little bit now. I initially thought it was bryopsis but have tried fluconazole with no luck. I have tried manual removal which will remove the amount initially but always comes back. I have also implemented reduced feeding by reducing total...

I just got home from a trip and noticed some small black dots on a little frag I have. Does anyone recognize these? My first thought is a flatworm or something but I can hardly see them. I took it out and dipped it as soon as I saw it, but I'm considering if I should dip the rest of my frags. I...

Hi guys, Got this cleaner wrasse yesterday from lfs, and I'm not sure if it's a false or true cleaner wrasse. So far it cleans some of my tangs and blenny. My mimic tang however does not like him and does not let him clean him. I tried to get a few photos or cropped screenshots from video...

I've caused some controversy over on reddit, trying to get some advice on why the head on one of my corals died. Instead of that, its turned into a large ID debate lol. This was sold to me as a Galaxea, but many are saying its a torch. If it is, it was definitely not priced as one ($15)...

Need help identifying what this is on/happening to my frag. Parameters are ph 8.2, temp 25.5 c, 1.025 salinity, 430 calcium.

Need some help identifying. Thanks in advance.

Hi guys, got this extra coral as a freebie in a recent order, but it isn’t one that I recognize. Any ideas on what this is? I took one picture under blue light and another with the orange filter lens for better color accuracy. Thanks I’m advance!!

Hello, this is a 13 gallon 2.5 year old tank… only pest I have that I know of are bristle worms however I just noticed this attached to the plug of a bird nest coral. Would this be aptasia? And if so how do you recommend I take care of it, the coral isent doing so well so maybe take the whole...

it wasn’t this big when i got it. it just kept growing more and more till it got to this size. and to be completely honest, i kind of like it and would probs prefer it to be on its own with no zoas.

I woke up this morning to find half a dozen of these guys (various sizes) on my glass today. There was also one floating around in the water - a clownfish took a bite, then spit it out. The crazy thing is that I haven't added anything new (aside from RODI water) to the tank in four or five...

I had only turned on the lights to try for a better picture. Only one rock and back glass seem to have hair. The rest of the rocks are just greenish.

I’ve been battling amphidinium dinoflagellates for a while now and just noticed some small round bug-like creatures running around on the Dino’s, I’ve never observed anything like this, they move quite quickly but not like copepods do, any ideas?

I was sitting at my desk last night and saw this little crab crawling pet of my live rock and I did some research and I looked like it might be a baby teddy bear crab? I am not sure and would appreciate some help in identifying him. Also is this a good or bad hitchhiker? (I know it’s hard to...

Hi guys just picked up this little guy this afternoon and was labelled as a percula, I have my doubts and am thinking that it could be a ocellaris. I liked him because of the unusual broken stripe in the middle so am happy with my purchase either way but just interested on what you guys think.

Hi there, have had slightly cloudy water and took a sample to find this guy. Not sure what type of algae this is. It has at least 2 Flagella, and is present when the lights are on. No sign of slime. Moves quickly as well. If anyone has any idea what genus this belongs to, that’d be great! Oil...

Hi I just got a new gorgonian and it's my first coral in my seahorse tank. I'm curious to know the identity of this species as I'm unable to find it anywhere and the lfs I got it from only knows that it is a nps Gorgonian. Any help would be appreciated

Posted are a few photos of what I believe to be either spionid worms or vermetid snails. I am leaning towards the spionid worms because I have not seen any “web like” material come out of the end, but if anyone knows please let me know? if they are spionid worms, are they harmless? Thank you!

Hello all, Please can anyone ID these 2 corals (multi-headed and 3-headed) I do have an idea but I don't want to bias any of your thoughts!

Please help identifying these Dino’s. They rapidly move and zigzag back and forth. Im at a loss I just hope they aren’t large cell. I tried to upload a 10 second video but for some reason it isn’t allowing me.

Hi, I am looking for an ID on this clownfish (the smaller one of course). is it a Picasso or an Onyx Picasso and how do you tell the difference?
