pest id

Hey! Tank has been up and running for about 5 months, so still a bit new to some (a lot) of things. Have seen these guys skulking in some of the rockwork before, but never out and about. Just tonight was alarmed to see them crawling all over my hammer. Managed to grab a couple out, but still at...

These clear "tube" critters have almost completely taken over the rear chamber of my nano AIO. They're growing and attaching themselves to the glass, heater and temp probes. I've also started to notice them growing on the rock in the tank as well. They seem to soft tissue and not hard, they also...

Discovered several of these on my rocks which i think are some type of snail. Had a couple of frags one one side of the tank die the past couple of weeks so I’m not sure if this may be related. Any thoughts?

Can somebody ID this worm? It is under 50 magnification. The two pictures are two different but the same. They look like bristle worms but very small. It came out of one of my large goni that has been receding over the last 3 weeks.

Coral Only tank, no fish/inverts. Any idea what this little tentacle is? I recorded one of them but I see 2 short ones and 1 slightly longer one. If a pest, any advice on how to remove it?

Hello all! To be honest I don't know how to describe these things. They look a bit like tiny pineapples that are completely white. I have attached a picture to help. Now that I have spotted them, I see that there are tons of them. Does anyone know what these are? They are approximately anywhere...

I bought some corals that I’m pretty sure are maricultured. And this frogspawn as these unusual encrust meant that I wonder if it’s flatworm eggs.

Hello all! I have seen a few of these small inverts that seem to have a hard shell like a snail, but they are not what I think of as the classic snail shape. They are long and oval shaped. I have only seen them under frag plugs and on rocks etc. This morning one was kind enough to be on the...

Hi So just got some montipora setosa, it's been doing fine for a week. Today the polyps where mostly closed, and can't remember seeing this white on it before. It's very very small, is it a nudi baby?

Good morning! These hairy tubey things have started appearing on some of our corals and there's one just sitting in the sump tank glass bottom. Just wondering if it's something harmful or if we should leave it be? Any ideas as to what this might be - sorry this is the clearest picture I could...

Hello! Rescued a sizeable pectinia that had a couple pests on it. It had a large vermitid that I glued over, a majano which I injected with lemon juice and covered with CA glue. There is a red sponge which I hope lives! BUT...What's in the picture? It looks completely different from the other...

Hi I have noticed these strange critters. Almost look like little flatworms but move like copepods they are dark red towards black to look at under blue lights. I think they are causing some tissue recession at the base of my acros and my candy cane coral? Or they may not be a pest and the...

I was looking at my tank at night and noticed this coming out of one of my torches. Couldn’t really figure out what it is. If anyone could identify I would greatly appreciate it!

Hello everyone So in the beginning of February I broke down my 75 gallon display tank bleached all the live rock except for one that had a mushroom coral attached to it. In preparation for my 125 gallon upgrade. I removed some substrate along with that rock to house long tentacle, my bubble tip...

Hey all, This is my first post on any kind of forum, so I apologize for any mistakes. I discovered this little anemone 3 months ago and have been struggling to ID it. It doesn't look like aiptasia from pictures I've been looking at but I'm still fairly new to the hobby and haven't seen aiptasia...

Hi all! For a little while now, my torch has had this clear white spongey stuff growing on its base and the past two days the torch hasn’t been out as much. Last month, I took it out to dip it and I carefully used a knife to scrape this stuff off. It was crunchy and sponge like but I managed to...

I noticed something that looked like snail eggs in my overflow chamber last week when I did a water change. I scraped it off and wouldn’t ya know I have at least 10 in all 3 chambers of my Evo 13.5. At first it reminded me of the ramshorn snail egg sacks in my freshwater but on closer inspection...

Hello I dipped some zoas in Bright-well Aquatics Koral MD cause I found some tiny critters on the rock of the zoas. Not sure what type of pest these are or how to get red of them since the dip did not kill them. Can you help me ID these pest. They have a pair of white antennas. Also found them...

Hey all! Relatively new to the hobby with less than a year of experience. Noticed my lepto wasn’t looking too hot and shortly after, I noticed these guys hanging out on the underside of the frag. My searches through the forums lead me to believe they’re hydroids, but I was hoping someone with a...

Hello fellow reefers! I noticed some white spots on 2 of my acro colonies and snapped a piece to inspect under microscope. The appear to possibly be eggs from something but I truly have no idea. I added some Berghia Nudis a couple of months ago, eggs look similar but smaller Any help will...

Hey all, I've got a sixline wrasse thats been in qt for 2 weeks now. Just this morning I'm seeing signs of what I believe are internal parasites? Tank started at 1.018sg and has slowly been rising due to evaporation, close to 1.021 at this point. Can I please get confirmation on if this is...

Found in my sand bed. Never seen anything like it before.

Hey, just saw these little guys on my glass today anybody have an ID? If it helps, I’ve seen my clowns and six line wrasse picking at the glass which I now presume is them having some lunch

I have a couple frogspawn that haven’t been doing well. I’ve noticed what I think are some kind of burrowing worm, but I can’t find any info on it. I see lots of posts discussing burrowing spionid worms in SPS, but nothing about euphyllia. I do have a couple SPS frags with those, but what is...

Hey all, I added a Torch to my tank about 4 weeks ago. It was doing great and seemed to be adapting fine to my tank. Lately Ive noticed a couple things of concern, could someone please try to identify and let me know if anything should be done? First there is this hair like strand coming off...
