I have a small queen angel in my 150 gal. I have had her about a year and at first she didnt want to eat but once she started eating she hasnt stopped. She would swim up to me whenever I entered the room and would pick at nori that I held in my hand. Last week she started acting afraid of me. She hides behind the rocks whenever she sees me. Yesterday she refused to eat for the first time in almost a year. Today she took in some food and spit it out after a few seconds. All parameters check ok and the other fish seem fine and are eating as usual. I am thinking maybe she has flukes? Would treating for flukes be a good idea? Any thoughts would be greatly appreciated.
