So this fellas is growing....fast. Like in a couple days double in size and showed up from nowhere. Any ideas? Growing on an Acan skeleton.

Hey guys & gals , happy weekend, hope everyone is doing ok Recently found this growing underneath one of my scolymia, appears to be some sort of sponge / truncate but wanted to post photos just to make sure it’s not something more invasive which warrants removal Here is a photo (attached) the...

Any idea what this is? I just got a frag today and not sure what it is. The coral is a red monti

Hey guys so I recently went on vacation and left my my mom in-charged of my tank. It was a week and everything looks pretty normal but I was inspecting my alve today and realized some worms appeared on the skeleton. I’ve had the alve for 4 months now and it’s been growing well. Any thoughts on...

Pest Identification! Currently in QT. Purchased a small rock yesterday from a reefer with a couple of shrooms and so far have removed Asterina stars, I see small snails, flat worms of some sort, and a long white Nudi or worm of some sort with a spade shaped head. I’m planning on a Bayer dip...

I was cleaning my coral with hydrogen peroxide solution and 2 worms dropped from the holes. I don't know if it is a bristle worm which became fat due to hydrogen peroxide or it is my nightmare: a fireworm. If these are fireworms are there any easy hacks to get rid of them.

Hello, Could someone help me with an ID on this flatworm? Maybe 1/4” in size. I have a fairly new mostly lps tank, I have recent lost of hammer which was doing really well for the first few month. I woke up one morning to a head with exposed skeleton, I took it out to dip the coral again (I...

Hey there I have a 35 dsa lagoon tank and in the recent weeks I’ve had these random things pop up not sure what they are. I asked other forums and no one knew any help would be appreciated thank you !

Lots of fun surprises tonight while cleaning the back glass, lol. I've been leaving it alone for a few weeks because I didn't want to bother the frag racks but it was time. Just got this adorable Frammer 2 weeks ago and it didn't have these. I don't think it's Spirorbid Worms but I'm not...

These little white-gray friends are spreading rapidly through the rocks. They dont look like they move (aka dont look like barnacles) and are a bit see-through. Some of the corals that are in contact with these are a bit angry. Anyone know what it is and how to get rid of it?

I had had got back from the lfs, I noticed this and asked one of the employees but they said they didn’t know either but I know it’s been there for a bit and hasn’t seem to bother the coral It has a clear tentacle spurting outward like a worm not really sure what it could be, there’s more on the...

Hi all! I have seen baby aiptasia pop up in my tank very infrequently, I usually spot about 1-2 a week (if any at all) and I’m a person with really good eyesight. These baby aiptasia have always been on a rock or frag that I was able to pull out and treat out of water, however in this case, I...

I kept observing everyday and I didnt see any sign of it, but after a short travel I see packs of flat worms on the polyps of my goniopora, I took a video of it, but they are literally all of it. I am assuming these are the harmful flat warms and should be dealt with? If I am correct what would...

After being visibly pest free the past year I believe I’ve just spotted a fireworm. Can anyone brighten the night and say it’s a bristleworm?! If it is a fireworm, I plan on swapping out my scape to all new dry Marco rock - didn’t want to change the sand though. Any suggestions?

About a month ago I noticed white specs appearing on my ulva and chaeto in my sump. They’ve now grown to be quite large. Initially I thought they were trochus snail offspring, but I am more concerned now that they might be a pest. They are eating holes through the ulva and have almost devoured...

I have these little dudes in quarantine and wasn’t able to pop them off their plugs. These survived their dips and I’d like to know what hitchhikers I’m dealing with as my display tank has none! On the acan hitchhiker one is part of their skeleton. On my encruster, hitchhiker 2 are on bottom...

I woke up a noticed the head of my rhodactis coral to be eaten or gone. Does anyone know the reason or cause for it?

Hey guys I just got a new hammer and Duncan from my lfs. After I dipped them these little worms came off the hammer. Are these the flatworms that eat euphyllia? What’s the next move on this?

Noticed this patch of zoas tonight after a herm ran them over. Seems to be quite a few only on this portion of the rock growing all around the base and stem of the zoas. Any ID help would be much appreciated! Thanks in advance!!

Saw this on my damsel this morning… impossible to catch the fish so far ☹️. Can anyone tell me what type of pest it is and if it’s going to come off on its own?

I just got home from a trip and noticed some small black dots on a little frag I have. Does anyone recognize these? My first thought is a flatworm or something but I can hardly see them. I took it out and dipped it as soon as I saw it, but I'm considering if I should dip the rest of my frags. I...

Hello, Just noticed this today. Any idea what this could be? Should I remove asap? Total size is about 2in wide 2in tall. Thanks

I’ve just bought a pyramid algae snail (tectus snail) from my LFS, i put it in my tank and i’ve come to realize it has this weird looking thing on it shell. Whatever it is seems to retreat quickly back into a hole in the shell when i move the snail when it feels endangered. can anyone help me...

Hi guys. My tank has been running about 3-4 years now. I haven’t seen these worms at all really. In the past few months their population has increased rapidly. Are they bad? I’ve had a few polyps die off on my LPS, but that could be from something else. Are these things bad? What are they?
