Not sure the best way to explain it but...I have these weird clear/brown things with a round shape at one end and a pointy head that stretches out to make him about 1" long. They don't seem to do any harm but they're creepy what are they?!
Most likely they are planaria (I'm going by shape and size description not by the color) which generally are harmless to the fish. However they are a sign that you most likely are overfeeding and are not keeping your gravel clean enough.
If you do a google search for planaria you should come up with tons of pictures of them, then you can verify if thats what you have. I would cut back on the feedings and step up your gravel vacs. Just be careful you dont do too much at once or you may send your tank into a mini cycle.
