I have a 75g set up for about 3 months and yesterday I noticed the larger of my two clownfish not eating. Usually the larger fish is a robust (read pig) eater. The smaller of the two has never been as big an eater but now both cannot be enticed to feed. The parameters are great everything is zero. Ph is 8.2 temp 80, sg is 1.025 alk is 3.5 meq/l and ca is 400. They do not show any signs of any parasitic infection and all other fish (yellow tang & diamond gobie) are doing well. The only thing that has happened is the frogspawn that they normally host was pushed out of it's niche by a turbo and I moved it about 6 inches away then it got moved again and I replaced it in it's original spot. I also noticed that a small green star polyps that I had has closed up and won't open. It looks like it was eaten by something. All other inhabitants are doing great eating and swimming. They (the clowns) hang around the bottom corner and don't move very far away. I can't seem to get them interested in feeding. I have tried mysis, brine, soaked in garlic and unsoaked. Normally they run to the baster when I bring it out. She seems sluggish but her eyes are clear and not discolouration or spots on her.
