Hi, thanks for reading this as it is my first post. I have a common plecostomus that is approx. 4-5 inches long. We have recently started implementing his diet with algae discs, and I have noticed that all day today he has had a very long strand of something coming from him. It has been atleast 8-9 inches long, and it got stuck to the filter. Eventually it fell off, but then he produced another one of the same length. I have never seen him do this, and if you can't already tell I am a first time aquarium owner. Any help as to what it is(I think it is a form of waste), and if it is normal would be awesome
. Thank you.
