We have received a lot of interesting questions about worms – that’s just what happens when you manage a website that invites reader questions about worms – but the query we were emailed recently has to be one of the stranger ones to ever arrive in our inbox. Here is the question: “I have a worm that looks like a goldfish. Very unusual looking. Can you tell me what this is?” A simply worded question, to be sure, but its simplicity belies the difficulty of answering it. A worm that looks like a goldfish? Huh? We have never heard of such a thing. In fact, we have never heard of any sort of worm that looks like a fish at all.
