bugs

I just saw some very small critters in my sand. They were moving and now stopped. Any idea if its good, bad, should i remove them?

Okay so I finally got the right kind of interceptor for my black bug issue. Let's hope this works. They are on my zoa's most of my montipora and some acros. They have killed my forest fire digis after smothering them. I've used coral rx and the Bayer stuff to kill them and I saw how many there...

Hi all, Very new to the salt water hobby and have no idea what these things are. Both have been found today (at night if that helps). One is a little bug and there seems to be a few of them. Large enough to see comfortably, roughly 1cm. One looks to be a worm/ tentacle with legs potentially...

I’ve discovered there is some sort of inscect living under my gsp frag have only noticed it today I’m new to the hobby and never dipper my coral before placing them in my reed can someone please explain what this is and a solution if necessary thanks

Hello, I'm (once again) struggling with poor PE and some tissue loss on my Acropora. First of all my tank parameters and my setup: 430L Tank Volume Very recent ICP: https://lab.faunamarin.de/de/share/analysis/115340 KH, CA and Po4 are fairly stable and I measure about the same as the ICP...

My favorite torch started to retract a bit recently, and after dark I shined a light on it to see these little critters. Gave it a good dip and moving it to the bottom of my sandbed to recover until I get it into a clean tank I'm starting. Does anyone know what these are? I don't have acropora...

Hi I need help identifying this bug? Please help

Need help, are those bugs good or bad ? Only see them when its dark.

I just recently noticed these. Seems like my clown fish are eating them, maybe?! I did drop a cube of PEMYSIS in last night because my new clown fish seem to not like pellets, but that is a different discussion! Any help would be greatly appreciated! Should I be concerned? Thanks,

I've been following this forum for a couple of years, but never posted before. Today when I did my water change, I found several of these black bugs crawling on the filter socks in the sump. Is this a copepod (didn't think they were black) or something more nefarious? Thanks for any help.

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?

Hello! Is anyone able to identify these brown spots on the base of my torch coral? I’ve been dealing with receding flesh on all my torches and I thought it was a phosphate problem (hence the heinous amount of hair algae) but I’ve got that down to a manageable level and the flesh on torches is...

Hello! Over the last couple months Ive noticed a couple of these black/brown specs crawling around like bugs and for some reason the first coral I noticed them on has been having very slow tissue recession but still has great polyp extension for now, however I noticed it receding more and...

I couldn’t figure out why my Duncan is receding so I put my camera on it for 9 minutes with flow on and off throughout. Tiny pods like creatures are running around at the base and I think those are what is irritating it. Does anyone know what these are?

Hello, 2 weeks ago I noticed that tiny creatures (about 1mm length) in my tank and now there is a plenty of it. They live in sand and they mostly appear at night moving quickly even over rocks. Can you help me identify these organisms?

Late at night if I focus my vision on a single rock I’ll eventually notice these little critters. They kind of look like little bugs. Any clue as to what they are? Are they an issue or just beneficial biodiversity to the system? https://youtube.com/shorts/RLRCAgm4sjw?feature=share

Hi all, I’ve had my reef tank for about three months and yesterday I saw a pink rice size thing floating past me in the water. It looks like a piece off a torch coral tentacle for the cooor and thickness. But this morning, I noticed it has attached to my glass and Found a second one. I’ve...

Bought a new hammer coral today and noticed at home it has black dots/patches on its skeleton. Gave it a dip and scrubbed lightly around the black spots and two little bugs came out which I'm having trouble identifying with Google. Could use some help and any info on why the skeleton has black...

There is a bunch of these little organisms that kind of reminds me of a snail or a slug, They are quite small, I tried figuring out what they were online and I can’t find anything on them. They have a tail with two tips and look to be moving vary slowly. (the thing in the center )

I try to look at my tank at night when everything is off because that’s when everything comes out, I saw these crawling all over my frags of zoas one of them is kind of fluorescent with I did not like because dosent that mean it’s eating my zoas? But they just look like pods of some sort to me...

I have a swarm of free swimming little white bugs in my tank and it’s tripping me out. They look like little white shrimp but hang upside down like mosquito larvae. Are they some type of pod? Or do I have a problem?

I was just looking at my tank and just noticed a bunch of these white things I have no idea what they are they kinda look like small snails I have not added anything new to that tank in a long time just have two clownfish and water perimeters are all normal

I was cleaning one of my tanks and decided I might want to do some reworking of the rock. All was fine until I moved one of the foundation pieces and ALL OF THESE LITTLE THINGS CAME SQUIGGLING OUT ALL OVER FROM UNDER THE FLAT PIECE. I thought it was bristleworms but they also kinda look like...
