How can I reach your levels of trollingPosted on ResearchGate forum and just got a response from a scientist guessing what species these parasites were that most closely matches what was in my old tank. Faciola gigantica, Fasciola hepatica, or some sort of related parasitic flatworm seems to be the most likely candidate. Apparently these things can cause tropical fasciolosis if you eat them. They have several intermediate larval stages of various forms that look similar to what I saw and normally use various species of freshwater snail and intermediary hosts before infecting cattle, sheep, goats, and other similar types of large mammals and birds in their final life stage. Experiments have shown they can adapt to other species of intermediate host snail. They are adapted to surviving in acidic mammalian digestive systems, which could explain how I saw them survive in my soap dispenser and salt water aquarium. Terrifying little creeps.
