Goldfish "fluttering" her fins
We have a comet goldfish that is about 3 years old in a 60 gallon tank. Just recently she started fluttering her fins (spastic up and down movement for a few seconds at a time). She started with just her top fin then we recently noticed that she'll "flutter" her bottom fin as well. Any ideas on what this could be? She's 5 to 6 inches long.
