When cleaning the gravel in my 10gl guppy tank, the other day I sucked up hundreds of these teeny little white wiggely things that looked like string at first! I found some swimming in the water and climbing up the glass also. As I use a turkey baster for the 10gls, these was easily sucked up and disposed off. Are they the result of not cleaning my tank for three days , as I usually clean them every other day and maybe overfeeding the tank? *c/p* Any and all help is welcome! thanks , Cindy
