I was watching my nassarius snails move when I put food in the tank, and it looks like some of them have a browish yellow flake like thing attached to their tails.. is that normal anatomy? Or is that a flatworm or other parasite and how Do I go about it? Thanks fellas I attached videos

I have some acros/Millie that started looking bad. I dipped one and these worms came off they don't look like planaria though I do believe I have some in my tank. What is the best course of action?

Cheers, all! I am moving a pair of clowns and a cleaner shrimp (with a couple of snails) into a new and cycled tank. The current tank has been neglected (by me, not intentionally) and is riddled with cyano, nuisance algae, and flatworms (NOT acropora munching ones, thank goodness.) I have...

Hi, Today, while cleaning my tank, I noticed something that looked like a flatworm, though I’m not sure what it actually was. It appeared in a group and was difficult to remove,I had to use a scraper to get it off. Does anyone know what this might be? Thank you for your help!

I realize I'm not going to win any Pulitzers for my photography here, but these popped up recently enough that I noticed them just 20 minutes ago. I have never had an issue with flatworms other than the ghost ones that don't cause issues, and that was years ago. I haven't added anything new to...

My two clownfish have suddenly developed small black spots across their bodies. I’ve had them for about 3–4 months now, and the onset of the spots seemed quite sudden—after first noticing one or two, several more appeared the very next day. The larger clownfish is behaving normally, showing no...

I’m new to saltwater aquariums. I received corals two weeks ago and they’re still in my corantine tank. Recently, I’ve started seeing a small creature. I’m not sure if it’s a flatworm, copopod, or something else. Could you please help me identify it? Is it safe? Should I remove it to prevent it...

can someone help identify what kind of flatworm are those? They are staying on flesh of torch and causing it to shrink. Flatworm exit does not work, I put 4 drop in this cup and nothing happened.

These tiny guys have appeared all over my glass overnight… looked it up and it seems like flatworms… Seems like it’s one thing after another. Had a brook outbreak while out of town a few weeks back and killed all my fish. My tanks been fallow for about 3 weeks (besides the corals, CUC, and...

My question is what type of flat worm this is and should I just toss this frag. I just ordered 11 frags from this vendor and have 9 other frags in qt. Obviously going to dip and scrape the frags before placing in qt. The frag was marked freebie and appears to be a favia or something similar...

Hi reefers, wondering if anyone can help ID flatworm. Found them when dipping my new acro in quarantine system. I’ve been dipping them weekly for almost 2 months, and there are still some fell off after the dip. I think they’re acoel as their have swallowtail, but would like to confirm it.

Hi all, just recently found flatworms in my large frogspawn colony. Dipped it and about 7-8 small flatworms popped off. Inspected after it was back into the tank and nothing. I wake up this morning to check and now I see them on my green octospawn. Was curious how others approached this fix and...

Hi I have noticed these strange critters. Almost look like little flatworms but move like copepods they are dark red towards black to look at under blue lights. I think they are causing some tissue recession at the base of my acros and my candy cane coral? Or they may not be a pest and the...

I found this little creature crawling on my glass at night, and I believe they’re flatworms. Can anyone help ID this? Or at least tell if they’re harmful or not? It looks transparent/white with black dots on them. Doesn’t look like brown flatworm unless it’s a baby.

Hello, I was hoping to get some opinions about what type of flatworms these are.

This flatworm looking creature came off my lettuce nudibranch. I purchases this nudibranch about a month ago not really any problems with it until now. When I was checking the tank a lunch it looked as if it had laid eggs. About 3 hours later this thing has been moving around the tank. The...

Are they compatible? My sixline wrasses doesnt go after the flatworms on the glass and they are getting out of hand. Need some suggestions to keep them in check. It is the smaller ghost flatworms, i mainly see them on the glass, tiny little guys. Flatworm exit doesnt really work on them, have...

Photo and video of flatworms link. These appear to be Planaria flatworms, but the only photos I can find are of RED Planaria. These appear as brown. Anyone know if this is just a variant? They meet all the other characteristics of Red Planaria.

I have started to see a number of these very small (1 - 2 millimeter) brown/orange worms on the zoa garden. Zoas seem fine. I collected one and put it in water on the top of a small plastic coffee lid. Photo and video below. I've read there are benign worms that match this size, but I'd like...

Hello, Could someone help me with an ID on this flatworm? Maybe 1/4” in size. I have a fairly new mostly lps tank, I have recent lost of hammer which was doing really well for the first few month. I woke up one morning to a head with exposed skeleton, I took it out to dip the coral again (I...

I had a bad problem with euphyllia eating flatworm, which ended up killing all my euphyllia corals. It’s been about 6 months, and the rest of my non-euphyllia corals are all healthy and I would love to get some torch corals again, maybe some hammers too. My question: is the flatworm still in...

Hello all! So I finally have experienced flatworms! I just spotted one a few minutes ago. I then sent him down the sink, and then immediately realized I should have taken a picture first haha. Looked online, and this is pretty much what he looked like. I looked through the tank and spotted a...
