Last night when I was looking at my nano tank I noticed this worm looking thing trying to swim around but it was being carried by the return’s current. I captured it and here is a picture and a video. Any idea what it is? Could it be a pod since I have seeded this tank. If not, is is harmful! Any input would be appreciated. I thought it may be a digitate hydroid but it was free flowing and its not very long..any ideas? I have a video of it moving around but I tried uploading but its not working. If someone can guide me on how to upload, I will, Thank you all in advance.
