Hi everyone I have a Annularis Angelfish or "Blue Ring" hes been in my tank for about 2-3 Month and he has suddenly just stopped eating. He was eating very well all the time. I got some newer fish and I dont see them ever picking or fighting with him He has no marks that I can see but i believe he is breathing heavier than he should be. I usually feed some coral plankton in the morning and mysis or spirulina later on in the day. I dont know if hes just in a mood or someone is bothering him at night or hes sick.. If any eyes or advice please.. I will be posting a video below.
