I was checking on my sump the other day and noticed something very interesting on one of the bits of rubble in my sump. I saw what looked like a feather duster or some other tree looking thing. To be quite honest, it looks like a white or translucent palm tree. Anyway, I shined a light on it to get a closer look at it and it retracted itself. It was pretty neat...unless it is something harmful. If not, I would like to move it up to the main tank. I will try and get a photo of it to help me identify it. Has anyone had similar experiences in their sump?
