Aquarium visitor… Leech?
Hello, I have just started keeping a fish tank, I have some young mollies that my granddaughter gave me last Thursday. This afternoon I noticed a slug like object halfway up the glass surface I took it out and it was soft to the touch, had a pointed tail and what seemed like 4 antlers on its head, It retracted its head very quickly. It was about 10 mm long, is it harmful to the fish and is there any fish that can be used to clear these up some one said a Skunk Loach. I am sorry I don’t have much information but as I said I am just a beginner. Thanks Mac < It sounds like you have plant leech. They sometimes come in with black worms.
