bugs

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...

There are thousands of these little white "bugs" crawling all over my live rock. Are these some form of copepods? Are these good or bad? (See attached video)

I have an emerald crab who always seems happy. He has already molted once like two months ago? I haven’t seen him for a few days and today I found him stuck to a rock. On further inspection it was either a molt or he’s dead. I’m not quite sure. I have a ten gallon with two clowns and some frag...

Hi, I'm new to the saltwater hobby and everything I see that I did not add to the tank freaks me out. I have these small white bugs on my glass I read about them and it sounds to me like some sort of copepod. I fed my tank cyclops at the start when I added my first fish as the banggai cardinal...

I have a new saltwater tank that is approximately 11/2 months old. It is 55 gallons, but I have 60 lbs of sand and 75 lbs of live and dry rock. I started with a bunch of live rock from a LFS with coralline algae and hitchikers on it. I did a fishless cycle. Dosed Fritz Pro Ammonium Chloride and...

I have a 16 gallon bio cube with no fish or coral right now. It’s been running for about 8 months. I’ve noticed tons of what look to be bristle worms and lots of other little bugs running around the sand bed. Want to be sure what they are so I can remove them. Couldn’t get great pictures though.

I bought a few Snails today and noticed one of them has white spots on it... I’ll attach a image below, any clue what this is?

Last night, the fish were swimming a little funny. I thought something might be off, but there was nothing out of normal. This morning, I woke up and noticed that all over the glass there were these hopping microscopic white bugs. Could they be affecting the fish? Its impossible to take a...
