Where in the world do they come from? They look like worms.
I guess they eat whatever I put in there, cause they are growin!

Yep they are filter feeders which is great because there cleaning the water for you They probably came as a hitch hiker on the rock you got and you didn't see it and they have grown.

Hope they are eating nitrates! I don't care how hard I try they will never be 0 again and my fish don't seem to care at all. I have a lot of coraline algae too
on the walls should I scrape that off or just leave it alone, kinda unsightly.

If it is sponges then they are filter feeders and good for your tank. Are they hard or soft? I was thinking maybe mini dusters if they are hard.
