Detritus Worms or Planaria?

[Courtneybst]

Hey guys,

I've recently spotted some bugs in my shrimp tank most of which are harmless. However, this worm-like one I'm not sure of.

I've whittled down that it could be detritus worms or planaria. They're so tiny so they look the same to me.

Any help appreciated.

Planaria have a triangular shaped head and 2 eye spots.

Detritus worms are thinner and usually in the substrate (but also found in the water column and on the glass)

Could it be a rhabdocoela worm?

Hey Nick,

I wasn't sure if you were supposed to be able to see the eyes with your eyes only or with a microscope.

These are on the glass, in the top layer of the substrate and I've seen some on the rocks too.

You may need a magnifying glass but the eyes are visible. The head shape is usually enough to confirm planaria.

Hi all,

I've whittled down that it could be detritus worms or planaria

<"Detritus worms swim"> in a wriggling (or corkscrew) motion and Flatworms (both Rhabdocoela and Planarians) <"glide">.

Try sucking one or two up with a pipette and put them in a smooth/round bottomed drinking glass, it makes them easier to see as the glass tends to magnify them.

Cheers guys, I'll have a look when the lights come on. I actually think I've got a magnifying glass around here somewhere...

In that case it's either Rhabdocoela or Planaria then. I'll let you know my findings.

As said planeria have a triangle shaped head and glide along the glass, i had somr and where quite thick, treated tank and seen none since.

Oh sorry I didn't update the thread.

These things do glide along the glass and hardscape but after observation I'm fairly confident they aren't Planaria. It appears I do have detritus worms in addition to this but their numbers have been dwindling after a lot of substrate vacuuming and I haven't fed the tank much.

So far no damage has been done so I'm not worried at this point. Will update if things change.
