pest

Hello, I'm new to SPS and ran into an issue with the 2 acros I've had for 3 months now. Everything was fine up until last week, one became completely stripped a couple days ago and now this one is quickly following. I had a doser go haywire (contained Tropic Marin all for reef) about 6 weeks...

Hi all, I just noticed this guy floating around in my water column twitching like crazy (sort of like a fish). Finally caught him when he was caught on a vermatid snail net lol. It looks like some sort of larvae, any idea what this may be? Thanks in advance!

Ok , so this won’t be to most people’s liking since there’s dif strokes for dif Folks. As reefers we need to be more responsible than we are. We need to start helping our fellow hobby members become better reefers through less miss-information when we’re telling someone how to deal with pests...

Recently discovered these black critters crawling in my tank. At first I only noticed a few, but tonight I decided to check on my tank hours after lights out and noticed a lot of them crawling all over the rocks and on some coral as well. It’s hard to take a picture so I attached a video link...

Hello and Happy new year Reefers. I am having a really painful issue which is aptesia is poping here and there everyday even after i suck them using a turkybaster. is there anyway to wipe out all without doing individual picking?

A few hours ago I had picked up a nice looking elegance from a LFS. The coral had been there for almost a month and looked beautiful. I took it home, drip acclimated, dipped and put the piece in my 125 gallon reef. About an hour ago from now I had spotted some claws coming from the elegance's...

All of my zoanthid frags starting disappearing over night and I noticed these snails a few days before I noticed my zoas gone. If anyone can ID them for me that would be much appreciated. Need to know if I need to completely wipe them out or not. Has anyone else had their zoas disappear within...

Hello fellow Reefers, This is my first time posting and need some help. I found this guy in my display tank next to a hard coral that looked like it had bees nibbled on. I put it in my sump for awhile before removing it to the toilet. Now I notice about what seems to be babies from this guy...

First post! Sorry its not a happy one :( I got home today and my clam that I have had for about 5 months now is gaping open wider than I have ever seen it. It also seems to have a bump in the center of the mantle as well. This weekend everything was fine and I even have pictures from then as...

I haven’t added any new rock or coral to my tank in months but today I noticed a bright yellow nudibranch about 2cm long moving across the back glass of my aquarium. The back of the tank is rarely cleaned so it wasn’t easy to photograph it through the algae buildup but here are the vest photos I...

I've seen a couple other posts like this one but none with clear answers I have a torch coral with the skeleton being disintegrated away. This torch is not the first lps to fall victim to this issue in my tank. I have a frogspawn that degraded all the way to the fleshy top. There is literally...

I’ve had him for over 6 months but last week the Zoa’s started closing and staying closed or dying not sure but I hope he isn’t dying. But this has been spreading from just two zoas to now what’s shown in the photo and I’m not sure what to do or what’s wrong I’m looking for pests but I don’t see...

All of the sudden out of no where I see this little guy. Should I be concerned? I know for a fact that I didn’t add him.

Hey All, I added a frag to my tank and have noticed some questionable algae. Can you please help me ID. I will share 3 different patches of Algae so an ID on each one would be helpful. To me pictures 1 and 2 look like Bryopsis and possibly 3 as well. If so, should I be removing the frag and...

What seems like clusters of tube/rod shaped eggs, open on one end, appeared quickly on open sand and a small spot on the base of a rock in shade within a couple square feet.. I thought nudibranchs but the mass is more of a wirey "neuron network" inside the cluster and could be a bunch of bugs...

Hi guys, I noticed this little thing growing on the side of my cane cane coral frag. At first I hoped it was a new head, but after doing some research I think that it might be a Vermetid snail. However, while it has the same general shape of one, it does not seem to have the hard, tube-like...

Recently, this pink/purple foam thing started overgrowing zoas in my zoa garden. What is it? What eats it or removes it aside from manual removal? Here are photos of it on zoa frags I removed to clean. I'm thinking it is a sponge. I have been removing the impacted rocks and frags and...

Please help ID this pests it all over my live rock. I’m looking for a fish or invert to eat it or kill it.

I didnt think much of it at first but now im starting to worry a little bit about whats going on with the base of my toadstool. I cant tell if its some kind of infection or if something is eating it away. Theres some sort of brown/red pod that i can only find on the stem of the coral. Can...

I have been suffering through a massive vermetid worm infestation in my tank for the past year. It all started from one vermetid worm that sneaked in on a Monti frag. I have well over a hundred worm shells in my 65G and have tried everything to include gluing, forcep removal, reduced feeding...

I was dipping my new christmas tree rock and this guy came running off. Want to play it safe so I have him in a breeder basket right now. Haven’t heard of any brittle star pests before, and I love to have them as they are great for taking care of detritus. Just want to know if it’s a pest and...

Hey guys. I just picked this guy up at my LFS. Guy said he was a pest hitchhiker so I bought it off him for a couple bucks. His body is probably about 3 inches wide not including the claws/legs. He's pretty big. He's munching on some octopus I just gave him. I bought it for my mantis shrimp...

I was dipping a few new frags today in Bayer and a second dip in Coral RX. I found this nudibract dead after the Bayer dip. Is there any way to ID the type? For those that don't dip new corals, this just goes to show why you ALWAYS should. This is a restart on a crashed tank (possibly due to...

Just researching the coral quarantine tank and thinking about the dipping schedule. I am looking at a fallow fishless, quarantine period of 76 days to rid the corals of the possibility of cysts hatching and infecting the fish in the display tank. Within that 76 days, how often, and with what...

Hello! -------------------------ANY INSIGHT WOULD BE AMAZING!-------------------------------------- BACKGROUND: I recently purchased a giant toadstool from my local LFS. Someones tank blew up in there living room and they had gotten a lot of corals/fish. Saw this giant toadstool he was not...
