hitch hiker id

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...

ID ?? Thank you in advance!

I removed a good sized chunk of a chalice that had overgrown a rock with zoas. Once off I noticed this really weird sight. Looks like purple blob that has a deep hole in it and orange filament running through it and don’t know what it is ?!

Hey guys, I have a derasa clam who’s been doing great for over a month now. The other day he developed a hole in his mantle — so I’ve performed a fresh water dip and relocated him )”(unsure if something may have messed with him). After the dip, I noticed a bunch of snail shells around him...

Anyone know what these hitchhikers are? One looks like a rolly-polly arthropod and the other a clear something—both came on a coral. Video link below: https://www.icloud.com/sharedalbum/#B0qGrq0zwGIRija

I'm new to this hobby and I encountered these on my newly bought corals. One lookin like feather potruding from torch coral, and the other one with a 2 antenna. Are these reef safe? What should I do? Thanks

I just found my first and hopefully my only Aptaisa! It’s on a rock that I can remove from my DT but the rock hosts one of my corals (can’t remember what coral my LFS said it was) I’ve had this coral at least 4 months but it’s just now made itself known. I’ve attached some pictures. Im new in...

What are these guys? How do I kill them dead? My new zoas won't open. I'm pretty new. Been reefing for about a year. I apologize if this is a boring/easy/already thoroughly covered question.

Anyone know what type of snail this is? Attached is photo and the eggs. I was thinking it was a stomatella snail but wasn’t to sure.

Just noticed this small brown thing with white/blue tipped tentacles on the glass of my NPS tank. Any clue what it could be? Sorry photos aren’t the best but curious if anyone recognizes this? Thanks

I found these guys all over my glass and this plug was a good spot for me to catch them on camera its a little tough to tell on camera which are flatworms and which are pods. The flatworms are dome shaped in the front with a split tail. Should i be concerned or can it wait until i get a little...

Hello fellow reefers! I noticed some white spots on 2 of my acro colonies and snapped a piece to inspect under microscope. The appear to possibly be eggs from something but I truly have no idea. I added some Berghia Nudis a couple of months ago, eggs look similar but smaller Any help will...

I was just looking at my tank and noticed a little star fish. What kind is this and is it good or bad?
