The first one’s stump me the most they are like a bubble/egg casing about 3-4mm in size.

First and foremost, my Duncan is closed because my shrimp decided to walk on it as I wanted to take a picture. Otherwise, no idea what this is growing on the base, I saw it before but it’s been getting bigger and bigger. It looks like some kind of worm so I’m a bit confused.

Interesting perspective After noticing an “asterina” starfish (I actually believe the are a different species) population starting to grow in a 1.5 year old mixed reef - I kept a close eye on my 2 colonies of illuminati zoas (as I started to see the asterinas sitting on zoas) I was able to...

I just saw this little guy crawling throw the gravel bed, hes approx a quarter inch long, give or take, milky white, with 2 stubby white antennae that appear like extensions of the carapace. i have normal copepods and he doesn't look like any of them. Any help would be greatly appreciated.

Second worm I saw like this. Looks almost like a bristle worm but it’s not a bristle worm. Anyone know what it is? I attached the video link below.

Found white cleaning out algae reactor, what do you guys think? Got him in a bucket rn . Aside from amphipods it was the only thing that stood out in the reactor

I got my first batch of coral frags on Tuesday. I dipped them using CoralRx put them on new frag plugs and put them in a QT tank. I noticed what looked like little white hairs or tentacles on the stony base/skeleton of one of the acan frags. I took some pictures to post to ask if this was normal...

I was doing my nightly hunt of Cirolanid Isopods when I stumbled upon whatever this is. Probably not the best video but wasn’t expecting to see it. Also is that a bristle worm it zoomed by or a fire bristle worm. I uploaded the video to YouTube

I was culling out some vermetids snails today when I noticed that there were some weird "bubbles" hanging off my zoas and some of the stems of the colony had turned yellow. I poked at the bubbles a little but nothing happened. Obviously I had irritated the colony so they were mostly closed .the...

I recently added some ocean aquacultured live rock to my tanks that came with all sorts of cool sponges tunicates etc. Added a really nice piece to my macro tank. I’ve noticed a few bristle worms crawling around when the lights go out which I don’t mind. I was checking for other critters last...

I found this little tentacled critter on the underside of one of my zoa plugs and when I moved the plug to look at it I saw sweeper tentacles come out of it. Should I forward it to the after life and scrape it off or leave it be?

Just found this in my tank don’t know if it’s bad? Hard to get a good view of it, if anyone could help that would be great, must be some kind of snail but I only have conches in my tank and is not like them at all

Found two of these guys right next to a new zoa frag. They might have survived the initial dip with DipX and peroxide. I know they are tiny and an ID might be difficult but I'd still appreciate the help! Are they sundial snails? There are currently astrea snails in the tank. I have recently...

I was looking at my tank at night and noticed this coming out of one of my torches. Couldn’t really figure out what it is. If anyone could identify I would greatly appreciate it!

Quarantining some snails and shrimp in one tank and crabs in another tank. Found a million of these with the crabs, and fewer but still a lot in the other tank. Any ideas? Mites? Copepods? Trying to see if I need to set up a fresh quarantine tank to get them out if they’re a problem. Picture...

I have noticed my SPS and some Millies struggling over the past few months. I have had red bugs before, and AEFW. But this time as I pick up the corals, dip them I haven't found anything until today. All of this came off just one Acro. I havent seen this type of black bug before and also found...

Can anybody help me identify what’s hanging out on this coral in the front? I just got it in. I know the one piece is bubble algae and I should just take it off but what’s the other stuff? Thank you!

Hi everyone, does anyone know what those are? I have seen around 3-4 of those around the tank, they are really small.

Hello Everyone, I just put some blue hypnea in my tank and see I have a hitchhiker that I am not too positive what it is. could this be a worm possibly a baby Medusa worm or something else? Your guess is as good as mine so I appreciate any responses. I have nothing but live sand, some asterina...

Hey all! I recently was cleaning my pump and noticed these weird white caccoon like things all over my filteration chambers. I can’t find out what they are! Anyone know ? If you do know, are they bad? If so how do I get rid of them?

Hey all. Been doing some research but can’t seem to find a great match visually. Is this critter good or bad? Majano?

Hello everyone! I just received an order of clean chaeto I ordered from algaebarn and there are some hitchhikers in the bag, are these pests and something to be worried about? Thanks for your time!

I noticed these weird worms? In my tank they eat food if I put it down there. They've recently been popping up all over the tank. What are they? And are they harmful?

I caught sight of these little guys in my tank this morning before I left for work, I googled around and I’m guessing that they’re copepods but I wanted to get confirmation that they’re not harmful. Tank is at least 6 months old (possibly more, I’m the second owner), and the parameters stay...

Guys!!! It’s been months! But I finally got a decent video of that darn work thing that’s always poking out the rock at night!!! It always comes from the same spot and seems to eat the left over food which is great! I am terrified that it’s going to take out some live stock though! Any ideas...
