Hospital Tank Creatures

[Mundeez]

Hi gang, wondering if anyone can ID these little brown critters crawling around the glass in my QT? They look like some kind of baby snail or flatworm perhaps…. But there are a ton of them crawling around the glass.

Hard to see in pic but I suspect copepods

They seem to move more like worms, but idk , may well be pods

look like Flat worms to me. Not good.

I've had these before, definitely not pods, the best I can describe them as are shorter versions of "detritovore worms" that people find in fw tanks.

They are harmless and I find them in newer tanks (and in this case, a new QT tank)

Unfortunately need closer clearer pics to confirm. Seeing chaeto in the tank may suggest they are pods and if you have sump- thats where you want the chaeto algae

I was able to get one under a microscope…they do look like flatworms to me…

Is that a QT for fish?

Those are a type of worm, detritivores. The question would be, why so many of them in a QT? They must be feeding on something, so that implies too much food going into the system.

Yes- has flatworm appearance
A couple of springieri damsels or 6 line wrasse should consume these but there appears to be quite a bit

I’ve got a yellow Coris Wrasse in the main tank, and only saw this population explode when I put a turbo snail in the quarantine tank. So I’m hoping that the wrasse is doing his job…. Although I have had a few hammer corals bite the dust….so idk

Or it implies no medication in QT tank

Correct, I was thinking that also, but neglected to mention that!

Oh you were talking about the big brown blurry ones and not the white squiggles on glass.

Are the white squiggles moving, or are they just remnants from sand/new water?
