I looked at the list of symptoms here and on other website, but I'm still not sure. Unfortunately I can't get a good picture of him because I only have a camera on my phone, and he is darting around. But I got Link a few days ago, and his fins are a light blue which fades to a goldish-green body (he is my avatar picture, if you can see him). He acted totally normal the first three days, ate fine, swam around and all that, but today something is different. I noticed a patch of shiny gold on either side of his head, and he is darting back and forth CONSTANTLY. He ate this morning (two small pellets), but tonight he completely ignored the food and continued darting (it looks almost like pacing). Is he sick?
