identify

It is a slow-moving worm with clear segments. I can’t get an image of it under a microscope at this time. I have found two so far on the glass. Could someone please help me identify it? Thanks in advance! Here is a video if you can view it

I found it on the shell of one of my hermit crabs. I thought it was just some antenna it was using, until I watched it switch shells. I removed the shell and placed it in a Tupperware. The tentacle(s) are those tiny white hair things coming off the tip of the shell, about the center of the...

I have been having this water surface problem. Some type of green film has been building up. Manual removal does not work; it just comes back in hours. Anything it touches (equipment, fingers, containers) it sticks to. Today, I decided to put it under the microscope. It is not algae. It is a...

Here is a video of what I am pretty sure is a pregnant copepod. Im unsure of its species, but based on its size it might be a Tigriopus. It looks to be about 1-2mm and I can easily see its body with my naked eye. Other than size, is there any other way to identify copepod species? Also, side...

This comes from a newly setup tank. I had the dry rock and water "cycling" in a container for about a month before add them to the tank. At that time I added the "live sand" (the kind purchased in bags). Few days later, added some fish, and fed heavily. Weeks later, added cheato and pods.. I...

i saw this thing at the wildwood crest beach and no one knew what it was, can anyone identify what this is

I acquired this birdsnest coral from a friend of mine a month ago, and it has put on incredible growth so far. These pictures are from June 5th and today, July 6th. I believe it was originally from top shelf aquatics. Any ideas what variety this is? He has a huge tank and buys a lot of corals so...

Hello! Hope everyone is having a wonderful day. I’ve seen this coral a few times but am having a hard time identifying it. I’m thinking maybe a patriot rainbow chalice... but some corals look so much alike I’m feeling confused. For now I call it the paint spill coral lol...

Please help identify what is on the right side of my montipora. I see a flat center with flat legs going out.

Any idea of the species ?

Hello! I noticed this white blobby stuff in my rock cave about 6 months ago, but couldn't find much info on it so I cleaned it out to be safe. It appears its back now though, and after doing some more research it sounds like it could just be sponged/filter feeders? Posting here to get...

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...
