Basically it feels like they all appeared over night. I just recently stocked my tank with 6 African cichlids and a Pleco. After feeding them frozen brine shrimp for a few days I started to get these white stringy looking things. They don’t move and basically just stay wherever they are. I’m not sure if this is fish poop or works or the left over brine shrimp I put in there. Really hoping someone could give me peace of mind and hope I don’t have worms on my hands. This is a new tank.
