pest id

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.

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.
