pest

i am looking for confirmation on type of sponge as well as what to do about them, I’m not worried as they are in my quarantine system, just curious as to eradicate or propagate lol, see attached below

I need your help! What are these tiny worms? I noticed a ton if these smaller worms, there are thousands of them. Looking for an ID on them.

I found this critter today. I am not sure what it is. Good or bad? Should it be killed with fire? Seems like a small orange worm with small white tentacles, or hairs, on one end and pointy on the other end. I hope the pics help. Thank you for your help!

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...

Hey folks! I noticed this guy cruising around my tank a few weeks ago. Didn’t think much of it, honestly. Thought it might even be a baby astrea but I can’t tell (mainly because I’ve never seen a baby astrea). It’s not causing any harm to anything in the tank, just cruises around the glass and...

I found this red limp in the back of my BioCube 32. It was solid when I pulled it out with a turkey blaster, and loosened up when I put it in a cup. It doesn’t feel like cyano, and it was only in one spot. Testing parameters, will update when complete.

Greetings - wondering if anyone has seen anything like these on their sps? Would love an I’d and eradication if possible? did some macro work and stumbled on them by accident. Coral rx Dipping does not seem to clear whatever it is. At eye view they look like small black “pitting”.

Just noticed it tonight but coming from underneath the piece of live rock that my new (as of 3 days ago) cauliflower colt coral (which I did do a coral dip for) is this greenish brown thing that was more "open" when I first spotted it and started hiding when I starting lighting it up with a...

Hi - I noticed these the other day but thought they were just little snail eggs or something maybe. Didn’t give it much thought but now I have way more on my glass (20+) and saw one moving around on my frog fish today so I got worried. This is the best pic I can get. They are much bigger than...

Hi everyone, need some help to ID what's going on here. Lost a few Acro to this. Seems to be STN? Does the decay pattern suggest pest? I have not seen amy red bugs or AEFW, just have some pods crawling on it lol. NITRATE - 2 Phosphate - reading zero, but pretty sure their a bit ALK - 8.6...

So have a hammer and it’s always had some “dark spots” figured it was some discoloration of some sort. After tonight looks like it has spread ALOT since I’ve last paid attention to it. Might someone know what or why there is some blue Something growing around my hammer? Got the best pic I could...

Hello! I’ve noticed this brown fuzzy looking thing popping in and out of a hole in my hammer coral skeleton (bottom left)I made sure to dip the coral before adding it to my tank, but I guess whatever it is, wasn’t phased by the dip. Any ideas what this could be? Is it harmless, harmful? Hammer...

Hi, I got a free colony of bambams and there's this yellow thing on it that looks like a sponge but I'm not sure as I have never seen one. I also dipped the whole thing yesterday so is it dead? It looks the same as it did before. Are these little things harmful and if so, how do I remove it? Can...

So i dipped my goni in some Melafix Coral Dip and these two things came out. I don't think they are copepods because they are at least twice the size of the ones I see in my tank. Any clue what it is? They look like little shrimps and but I really am unsure whether or not they are copeods. Also...

Anyone can ID this for me? Today one of my hammers died. Last night it wasnt happy and looked extremely stressed. Sucked to see it that way cause it was fine just hours before in the morning. So i dipped it in iodine and put it back thinking its a bacterial infection. At midnight i came down and...

I have done some digging and but can’t seem to identify what this is and if it is harmful to my tank inhabitants. Grows on glass, live rock, and shells and seems to move/ grow by the day. Any thoughts? .

So I bought a used biocube 32. I haven’t got any livestock or coral yet but I plan on a seahorse tank so anything that stings is a no no. As soon as I set it up I started seeing small bristleworms, too many to kill by hand. Now I’ve seen a really big one, and I’m wondering if there are any...

I have a Fluval Evo 13.5 that's been running for the past year, today I noticed these little guys all over my glass. I'm not sure what to make of them, I'm assuming they are some sort of a pest. I initially thought copepods, but I haven't introduced any to my tank - maybe they came in as...

Hi, I was doing maintenance in my tank and i noticed this little fellow lurking under a rock. It probably came with my live rock considering that I haven't introduced any corals yet. Should I be worried about it? Thanks!

Can anyone help me identify this and figure out if it is bad for the coral and my tank ?

Quite sure these little fellas came on some recent frags, don’t seem to be bothering much aside from me. curious if anybody can ID them, they’re extremely small, maybe 2mm and brown in appearance, I’m treating with PraziPro atm after seeing it irritates them in a coral bath, however they’re...

Hey All - Looking for some help in identifying a possible pest in my tank. These things are all over my glass and my zoanthid frag and showed up overnight. Tank is about 3-4 months old and added my first corals about 3 weeks ago. I did dip them before putting them into my tank (unfortunately...

This was burrowed into a coral I picked up today. Does anyone have an idea what it is? Coral rx did nothing for it.

Can anyone tell me what this pest is, and if it is a threat to my reef. It’s a very small white/ or translucent oval shaped pest. I’m seeing them on my glass as well as coral and live rock.

Please help with some advice! I have no clue what this is at all. It’s about 2 inches long at least. Has anyone dealt with this before? If so please help with some advice!! Very much appreciated!!! Thank you
