Hello! I have a hard coral that I got from a LFS about 8-10 months ago. I honestly do not remember exactly what this coral is, and would appreciate some help in IDing it. It is also starting to bleach from the inside out it looks like. I have had 0 changes to my tank besides add a couple...

Hi all - I have this purple-reddish algae covering all my rocks and filter equipment. I have read about cyanobacteria and coralline algae, but this algae does not seem to match either description. It spreads fast on rocks and hard surfaces but seems to stay away from my crushed coral substrate...

Please help me identify what type I'm dealing with. The video with loads of golden coloured ones is from my sand and the one with more red ones is from my rocks. Some of them move in circles.

Bought this piece of live rock, and wondering if anyone can help me ID what these masses are and what all is going on with it.

Just got some new gsp and planning to get it carpeting the back wall. Bought it from my LFS but a new person packed him up for us and they seemed very new and not sure of which coral was which and I didn’t notice this other coral (?) that was on it. Can anyone tell me what this is? Just want to...

Hi all, trying to figure out if I’m experiencing the start of dino’s in my system. They don’t look like dinos under the scope however they appear like them with stringy snot and looks as if they disappear when the lights go off. Hopefully the video is good enough! Thanks :)

What is this? I’ve added several different coals to my tank and I found this growing under one of the rocks. Does it look like green star polyp, or is it something else?

Hi. I got a tank from my co worker but it’s not what the box says! Tried finding specs online but nothing matches up with what I have. Narrowed down to a Red Sea due to the style, but I don’t know which model this is. The box it came in says JBJ 45G AIO Flat Panel, but it definitely isn’t. Pics...

Hello guys, New Reefer here. Please help me identify these. Worth keeping? Will they spread like crazy? Thank you all?

Need some help identifying this zoa. I got some GSP 2 months ago and there was a tiny little nubbin of a zoa in it. It barely looked like one, smaller than a pencil eraser. I seperated it and put it on a rock near my other zoas. Now its one of the biggest in my tank and I have no idea what it...

I know amphipods get large, but anything i've seen is like a flat looking shrimp. Anyone id this guy? Sorry about the videos, trying to focus on the sucker is hard.

LFS guy says 1. Favia, 2. Acan, 3. Acan Please help confirm. I have a 150g mature tank, just need to know the best placement for these guys.

I’m not totally sure what these corals names are pls lend a hand

Hi, Put a new piece of rock in the tank recently and this thing has suddenly appeared at some point today. Anyone any ideas?? It looks as though it’s “breathing” in the video but I can’t be sure with it being on the power head. Every days a journey with a new reef tank

Came in on something I bought at a swap. Didn't notice until next day so I'm not sure what it was on.

Hey guys, New to the forum and to salt water aquariums. I have a ~6 month old tank and I keep battling algae that does not seem to want to go away no matter what I do. It looks like GHA, but I'm now wondering if it could be something else. My nitrate is 10ppm and my phosphate is 0.05ppm, so I...

What are they and do the pose any concern?

Caulerpa Verticillata maybe? If so, does anyone have tips on keeping it in check without it taking over (besides kill it)? It seems to be thriving even in brackish water.

Hey guys, I was just wondering if someone could help me identify this “hammer” coral. A lot of the heads on the polyps differ from others in many ways. Just wondering if anyone knows why or if it’s a specific hammer. Or I’m just dumb, that’s plausible too.

It's hard to tell because he has characteristics both would have, what's throwing me off is his tusk is a light blue, is this an aussie or indo?

My wife purchased me a very pretty "mushroom coral" from a local fish store, my gut tells me its some kind of LPS but i'm quite new to corals and have just started getting beginner softies. I want to make sure this fella gets the proper care so any help and info would be much appreciated!

Can anyone please help me identify what I have growing throughout my reef tank? Are they going to become a problem? If so, does anyone know of a natural predator that would be reef safe?

It's been a while that these white dots started appearing. At first I thought they were copepods so I just let them be. But looks like they could be snail eggs or something. I have astrea and trochus snails, bristleworms, lots of copepods and amphipods in the tank so could be one of those...

Looking for any input on what this glass clinger is. Not sure if it is a trail remnant or a “live” thing? Such an odd skeletal shape. It just appeared one day on the glass (three days ago) and the same day my cleaner shrimp disappeared and hasn’t come back. The glass clinger hasn’t moved at all...
