Just did a change in my tank today and while changing the water/ gravel vacing adding a couple of rocks saw about 6-8 white worms about 1/2" or so long. Tank(75g) gets 2-3 water changes a week declor is Amquel+, Inhabitants are Pair of 6-7" JD's and a pair of bristlenose. Kinda unsightly. Just venting I know they won't cause problems but damn they are unsightly.
