Unidentified Worm-Looking Creatures in Tank

[crupp29]

I wasn’t really sure where to post this, but I just found some white worm-looking creatures on the glass of my 10 gallon. I’m not sure whether or not I should be concerned, but I thought I would ask if anyone is able to identify them anyway. An image has been attached, it’s the best one I could take. I set up this tank a little over a couple of months ago. It contains dragon stone, driftwood, plant substrate, and a few plants. The stocking so far consists of a guppy (I’m planning on adding more) and a nerite snail. They are not from the snail because I only added the snail last weekend (which wouldn’t have given it enough time to lay eggs and for the eggs to hatch, which they wouldn’t be able to do anyway). Any help on identifying what these may be is appreciated.

Does it have an arrow-shaped head? Or is it fairly symmetrical and rounded at both ends?

I had eggs from Nerite snail the day after I put them into the tank so I wouldn't say that it's impossible. Are they moving?

It could be something which hitched a ride on your plants. I had lots of fascinating little creatures all over my glass. They gave me something to watch while cycling. They've all gone now - possibly eaten.

They are symmetrical and rounded at both ends.

The main reason I ruled out eggs was because they were moving.

Hard to tell from the pic, too blurry...what is your feeding schedule?

My money is on baby snails.

I feed pellets 4-5 days a week, once a day and I've started feeding freeze dried brine shrimp 2-3 days a week, once a day.

Actually, I did see what I suspect was a baby snail a couple of days ago. It looked a lot more developed than what I found yesterday (I saw its shell). Also, the it was larger than these. I lost it before I could take a picture, but I assume it came on one of the plants I bought recently.

Maybe detritus worms?....common in overfed tanks...you are feeding too much for 1 fish, and a snail

Thank you. I did have a couple more guppies (all males) that passed and I'm not sure why because all of the parameters were where they were supposed to be (the tank was cycled before I bought any). This is the reason why I'm holding off on buying any more. I want to identify the problem (if there is one), which I would assume there must be. The guppy and snail I have now seem to be doing just fine. I have been feeding less than I was before, but its probably too much still.

Nerite snails will not hatch in freshwater. Hard to ID with the pic, can you get a short video of it moving?

In that case I think it's a Rhabdocoela flatworm. Harmless, nothing to worry about.
