Hi, glad to help. Do you have a quarantine tank set up? How long have you had the fish? If you don't have QT tank, you're going to want to get ready for a fresh water dip asap. Fill a bucket half way with filtered water. Make sure the water is the same temp as the aquarium. You're going to want to dip for about 3 minutes. Let me know about QT tank and fish history and ifbit has been eating.
