Hey everyone! Sorry, my message was supposed to be included with those photos but my post didn't upload properly: A couple of months I noticed that one of my goldfish had a clear/ white string hanging out of him which I assumed was just unusual poop. Throughout the last couple of months however, I have begun to occasionally see the same thing wrapped around the plants in my tank, laying on the substrate or floating around in the water. Two nights ago, I noticed HUGE grayish-pink poops all over the bottom of the tank, some clear hollow poops with black specks/ pieces in them, and the white strings on more of the plants (See attached photos). I have absolutely 0 experience dealing with fish parasites and diseases so I have no idea what their warnings signs are. Therefore I also am unsure what is causing this to happen - assuming it's not normal. Just some background, I rescued these 3 goldfish when they were tiny babies and I have been consistently upgrading their tank size as needed. They are currently in a 60 gallon with a Fluval FX4 filter and I perform regular water changes. They all have some white raised patches on their scales which I assumed was just from injury as they are sometimes aggressive towards each other. I am now concerned that it is something more serious. Also, one of the fish has much longer fins and she has a clear bubble on one of them, as well as some red streaks and white dots throughout the fins. I am hoping that someone with more experience with these issues than what I have can help me determine what is wrong and how to stop it. Please help!
