We had seven green chromis for about two years. 300 gal sps. We put a foxface in a few months ago. (Foxface was in observation for 6wks prior) All of the fish appear happy and healthy. About a month ago one of the chromis disappeared. Just today another did. Not sure what is going on. Foxface gets nori in the am. We feed a cube of frozen brine or Mysis most nights. They get a cube of cyclops one night and pellets another. The foxface eats some of the brine and mysis but not the other. Not sure what I am doing wrong. No big changes in chemistry.
