flat worm

Appreciate any help ID this stuff on this new frogspawn frag I got today. What is red spikey stuff? What type of flatworm? What could this tiny red worm be? Thanks so much!

Just noticed a few of these popping up in my tank i can’t really tell what kind they are and what’s the best method removing?

I was trying to see if anyone knows what these are? I wanted to see if they were flatworms and if so are they harmful to my corals? Hard to see I just noticed them today

White worm found in rock. I was chiseling away pieces of rock with mushrooms. He was literally running through the rock away from me. Found this massive flatworm in there too, 3-4”. What is the white worm? Peanut? This is the third predatory flatworm I’ve found in this tank. What is it, what...

Hey all, The pictures describe much better than I can. They look like some sort of flat worm that have attached to all my rocks in less than 3 days. There are well over 50 at this point, still growing and still multiplying. Please advise as to what they are and what, if anything, I need to do...

I’m having some really weird stn issues going in in my tank. It’s a 10 gallon and has been going good for a couple weeks i’ve been having some really bad tissue loss on some sps and some lps that i have no idea what it is or what to do to treat. 1.025 sg P04 0.00 (hanna phosphate ULR) NO3 8.0...

Hi Had flat worm in the past and got rid of them by using a pipet….. Anyway got a new coral found a few flat worm removed via pipet but accidentally lost 2 in rock work….. will these die, reproduce within rock work instead of the torch or make their way back to some euphyillia? Thanks

Hi Guys, I've had this "Mini SPS Colony" in my tank for about 3 months, it was growing quiet well to start with but for the last two months its been slowly losing flesh, I originally thought it was just down to shading so i moved it to pretty much directly under one of my lights to try and...

Is this a flatworm? My pocilipora has not been doing well, and today I notice these greyish things moving around on the coral. What do you suppose hey are?

Losing sleep sucks, especially if your tank causes it. You look into your reef tank, your worse fear is....? For me, it’s when I am 2 weeks without seeing a montipora eating nudibranch just eating away in my QT. ::gets out dip bucket and picks clean 10 frags::

By best guess is a baby flat worm based on images that I’ve seen from other people. Maybe a pod? if not, it’s my best excuse to pull the trigger and get a melanurus.

HELP! I thought these were the normal amphipods covering the glass of my frag tank, but I seem to have picked up flat worms! Are these dangerous or ok? If dangerous, what kind are they and how can I treat them?

So I just got some frags today from a seller who has flatworms. Excellent guy, he dipped the frags for me and did a flatworm XIT dip along with his regular coral dip while we talked. I further inspected the frags before adding them to the tank and couldn’t see anything on them (they’re small zoa...

So I think I have atleast 1 polyclad flatworm, I have seen what I suspect to be one, I didn't get a great view but I think that's what it was. I am going to make a trap that I have seen people making online but the only issue is I can't get any clams. Nowhere seems to have any fresh or frozen so...

Just like the tittle said i saw a bunch of these lil caterpillar pocket like thing across my liferock and its on my hob skimmer too, im not too sure if its flatworm or pods reproducing in tank (because ive seen a pod like creature crawling out of those caterpillar pocket). I can only take a...

Hey everyone, I have a 5 gallon reef setup and have some small brown flatworms. I don't have a ton so I'm looking for something, preferably an invert, that can live comfortably in the tank and help control or eradicate the flatworms. Any suggestions?

Does anyone know if I should be worried about these tiny flatworms? I took this video of them in my refugium with a copepod for size reference.

How apparently i have flat worms and if I'm not wrong, they're just a small as copepods if not a little bigger.....right? I have a TON of copepods in my nano tank which only houses 2 nass snails and a few different corals. This whole time i thought those were just adolescent copepods but if...

Hi, I just started finding these flatworms in my tank. They are normally on my live rock and not on coral. They have a hard texture, with a pattern on their back. Does anyone know what specie of flatworm they are, and if they’re something I should be worried about? thanks in advance!
