So I did a water change and good tank cleaning on Tuesday. Today when the lights came on I noticed several of these bright lime green tubes. I watched all day to see if something would come out of them but they just hung there. They were not there on Tuesday and I have never seen them before. Just wanted to know if they are good guys or the kind I need to catch and dispose of right away. Thanks in advance :D [IMG]http://i83.photobucket.com/albums/j294/lilyicu/CIMG8927.jpg[/IMG] [IMG]http://i83.photobucket.com/albums/j294/lilyicu/CIMG8926-1.jpg[/IMG]
