I found two of these at the bottom of my 29 g QT tank tonight. Having looked at scores of worm photos (and some things I can’t un-see) I don’t know what they are. Just did a 30% water change and plucked them out. They look quite flat, like a tapeworm, but they are at most ½ inch long. I’ve set them aside. They don’t appear to be moving. There was some normal poop I cleaned out but not a lot. Both fish (2x female Bolivian rams) seem okay but maybe not the same as I’m used to. Only had them 2 weeks but they were both at the front of the tank looking like they were doing the “feed me now” dance but I didn’t see either of them eat. They aren’t futzing through the sand like usual. One seems stressed after the PWC - dark colour bars but fins are not clamped. Params 0 0 5 after PWC temp 75 deg. Can anyone tell me what those white things are and what I should do about them?
