GardenStateGoldfish Posted July 7, 2021 Share Posted July 7, 2021 Hello All! I am looking for a knowledge dump on Helobdella europaea. I have read the only two scholarly articles I could find on them but need a lot more information. One, are they friend or foe? Two, are they dangerous to fish (seems like no) Three, are they dangerous to mystery snails? Are they dangerous to shrimp/crayfish? Are they dangerous to goldfish older then 3 months old? I have been doing some experiments with mine, I can confirm they absolutely pray on ramshorn and pond snails. But on mystery snails they appear to just sit on their shells? Are they not interested in biting they mystery snails? will they harm my goldfish? any information at all would be GREATLY appreciated. Thanks! The photo below is the actually leech I pulled from my aquarium (my photo) but I have since found more. Link to comment Share on other sites More sharing options...
