pest id

Hi everyone. Need some help with an ID on this guy, and if it's a big deal he's their. If so, best action to take? Thanks!

I bought some zoas from my LFS four days ago and one of them had these little red dots on them that I noticed after dipping them. I dipped for 30 minutes and blew water on them every 5 minutes using a pipette to try to knock off anything but these were left, I figured it would be okay since I...

I have a snail shell with a bunch of mushroom corals on it being used as a frag which I got for a freebie at my lfs as I wanted the coral BADLY!! But, the shell after being coral dipped already still has this type of bristleworm Inside it still... Could I get help identifying it and if it's a...

What is this??? I’m really concerned as it’s on my two headed HG!! Please the sooner the better I noticed today and here’s a picture of it!! It appears to be on the tentacle rather than flush with the flesh.

Hi all - there's a ton of tiny white things with feather-like heads growing on the glass and on the back of the tank. They look exactly like mini feather dusters. Is that what they are? Are they bad or indicative of anything negative? Included is a picture.

Hello All, I have found these things that look like red egg sacs growing on my montipora and on the rock underneath it. I have also found these white and yellow egg sac looking things on my elegance. Can someone please help in identifying these, and if it's a problem, how to fix it?

Sorry the image is blurry, my auto focus was focusing on microbubbles attached to the dipping container. I've done an iodine dip with no results on this polyp, and I just did a revive dip. I brushed a lot of the white stuff off. Doesnt look like nudis or spiders to me, and since it brushed off...

Was moving around my scape and just barely caught a glimpse of this guy and was hecka confused. Took a closer look and figured I’d just ask for help identifying it I’m thinking a pseudo but not quite sure.

I'm pretty sure I know the answer to this, but just looking for confirmation that these are vermetid snails I just discovered in my tank. I added some new zoas to my tank about a month ago and just noticed 1 of these on the frag plugs of 4 of the new frags. First saw them last night and they...

I got some corals from WWC about two weeks ago. I didn't dip them upon arrival as I'm new to corals... I've kept them in a separate tank to monitor them. Here's what I see so far in terms of possible pests/hitchhikers. If you can please help me identify them and possible remedies, I'd be...

Hello everyone, I saw this on a small piece of live rock, and I think it’s Aptaisia. I’m new to saltwater, and was wondering if I can just remove the rock and put another in its place. This has me worried because I heard they can be bad for coral, and I was preparing to get my first coral...

The Odd creature ever ;Doctor ;Doctor ;Muted ;Doctor ;Doctor Found this one on corals I bought from LFS. 1st I saw it on one Gorgonian Sea FAN and it was really strange, because the string coming out of there was over 30cm long. The issue I can have I don't DIP that particular Gorgonian...

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

I’m relatively new to marine aquarium keeping I’ve had freshwater in my household my entire life growing up but this is my first salt tank and my first to keep by myself. I had been given an “established” tank from my neighbor who had to move and couldn’t keep the tank. After doing weeks and...

Does anyone know if I should be worried about these tiny flatworms? I took this video of them in my refugium with a copepod for size reference.

So I decided to remove my PC rainbow to dip it because for some reason it was STNing and found this.

ive had this tank running for a year now soon to be a quarenteen tank for an upgraded yank. i had baught a coral from my LFS attached to this rock. today a week later i noticed these little guys. anyone able to ID them?

Found about 4 of these things in my sandbed coming out at night. White worms about 2 inches long or so. Any one know what they are?

So I’m recently returning to the reef tank world after a 15 year break. I’ve been a fan of R2R for months now and have just been hesitant to make an account for what ever reason until now. Saltwater is not new to me but keeping corals is, since I previously only kept anemones. I love the way the...

Hi everyone, Thank you in advance to anyone able to help me identify this thing. Tonight, I just happened to notice a bunch of these little guys come towards the light from my iPhone. They were very fast, and hard to capture with on my iPhone video. Any ideas? Would be good to know if they...

I passed by my tank when the lights were off and noticed these worm like things on the glass. I removed from what I can see but sure there’s plenty more. I do not know what they are or if they are harmful to my coral any information would be greatly appreciated. Thanks

Anyone help ID that these are vermetid snails underneath my new ricordea? Just notice it tonight.
