pest id

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...

Hello, any idea what this is, I have a 3 yr old ish tank and nothing is new and I haven’t really seen something like this before. Only pest Iv had are bristle worms. I noticed when I started to clean tank and small white tubes kinda blew around with the algae? Vermid Snails? If so what can I do...

I am dipping this chalice and zoa right now and there are alot of eggs on it. What could they be from?

The first photo the best I can explain is that it seems like they are eggs stuck to the glass. The second photo is a little harder to get. Basically what it seems like is a web of white goo. I thought it was snail eggs but it's been there for multiple weeks.

Hey all! I was doing a time-lapse of my GSP and noticed this thing coming out of it. I dip every single coral I have and I have no idea what this is. I took the GSP out of the tank the moment I saw it in case it's dangerous. Can someone tell me what this is? Bristle worms?

Got this snail i saw in my tank, tank just started up and is currently in the ugly stage

I have a chalice coral in quarantine and I'm noticing what looks to be small zoa polyps growing beneath it. Does anybody know what this could be? I'm really just curious if this could be some kind of pest. The chalice is purple and red but the "eyes" are growing green.

Frogspawn not opening

I thought the white stringy guy might be a bristle worm, but Im not sure

What are they and how to get rid of them? What product to use safe for fish and coral. Thanks

Hey everyone, Looking to see if anyone has a clue of what this might be. I have quite a few on different rocks in my tank. I’ve researched as much as I could and found nothing. Thanks!

Hi all, I am new to the Reefing Hobby and just stared my first set-up in November of 2022 with an old tank I used for freshwater (cleaned thoroughly). I do weekly water changes of around 15-25% but have never cleaned the chamber that houses my pump (including the pump) since staring the tank...

Hello. I have a 3 month old 20 gallon tank. Also I am new in this hobby. I got two corals of the same lfs. I found on one vermatid snails and removed them as soon as I understood what it was. Now I found at a similar area on that hammer coral small formations , 1 bud with 2 hairs/ filaments or...

Found this nudi just walking around on the side of the tank. I have put Berghia nudibranch in the system like 7 months ago but it really doesn't have the same colors as a Berghia nudibranch does. This one has red and a brownish body. I don't see any bit marks on anything just went through and...

Hello everyone, saw two of these guys on my rockwork and pulled them out of my tank. If you could believe after I got some photos and videos they started to fight and one got bit or ripped in half. Crazy

I've already removed two of these things from my tank and I'm pretty sure there is more. Straight up Killed or irritated some zoa's to death. Should I lose sleep?

Hey guys! My friend found this weird critter in their tank and we have no idea what to ID it as. Looks like some type of worm. Unfortunately there’s no pics of it in the water but I’ll attach a couple of pictures from outside of the tank. The spikes along it move almost like an urchins spikes.

So I lost a few corals lately trying to figure out is this is a pest they are the white ones next to my copepods about 4 times the size any help is greatly appreciated

Can anyone help me ID this crab and is it coral safe? I noticed my zoas have been looking poor and dissapearing and not sure if this guy is to blame. Video is attached along with some photos. cheers

I woke up today with these brown discs on one of my heads of candy cane. They appear to be moving and i just want to check what they could be and if they are pests. If so how would i go about removing them? Thanks (sorry for the dark image, lights just turned on)
