I have a foxface that has been pale in color for the last 3 days now, I don't know whats up and my parameters are normal. tested with 2 kits, my temp is 78 - 79. The only major changes ive done is adding a Snowflake eel, and fumanchu eel. I also added liverock yesterday to add more hiding spots, it helped a bit. I had to take the powder brown tang out, and they were always swimming together so does that may have something to do with it?
