Found this weird white growth? Worm? On my frogspawn. Honestly not sure what it is. Attaching some pics. Any ideas?

Hello everyone! This is my first time on a reefing forum. I made an account because I can’t find any information regarding what’s going on in my tank. 32 gallon LED Biocube All levels are completely fine and the tank is doing great other then the literal 2 - 300 slugs that seemed to develop...

I have had this piece for a few months now and it has been growing. Brief lighting issue cause some fading, but that was resolved and color returning to normal. I noticed the underside has a few areas that are open. These were encrusted when I bought the frag, so I know something is up, but I...

So here is a picture and a video of what they look like, I’m pretty stuck on what they might be. Does anyone know?

Can anyone tell me why these things are? There’s about 30 of them all throughout my tank, and they’re all about the same size. My friend says they’re aiptasia, but I like variety of opinions.

Hi all, I recently bought a new Acan and today I've noticed these arms growing off it that look similar to a colourless Zoa or Duncan head. One of them seems to have detached from the Acan and growing out of a hole in the live rock. I've never noticed anything like this on my other Acan that...

Hi guys. I bought a zoa colony from the LFS. A healthy colony. A werk later i noticed these tiny (5mm) fan like think protruding between the zoas. I thought it was aiptasia and tried aiptasia x. The little bugger was to fast and this was not successful. I then tried superglue. This didn’t...

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?

All of a sudden I have an infestation of very small brown and black pests that are scraping my rocks clean of all coralline, and attacking my acropora . Rocks looks bleached with blue streaks underneath. I found some from on A new frag weeks ago as it suddenly hade four on it, eating the acro...

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...
