Hi, I’m running a BioCube 32 that has been cycled for approximately 2 1/2 months. I added two clowns just after that and then a Yellowtail Damsel a couple of weeks after that. All the fish were acting and eating normal 2 days ago then yesterday one of the Clowns wouldn’t eat, or even come out for it. It was hiding and it’s colours are very muted, especially along the top of his body. He’s not gasping for air. I gave him a fresh water dip yesterday and after a little bit he was back swimming and enjoying life but this morning he was looking sick again. Any help would be appreciated. I’ve tried googling but nothing seems to match his symptoms.
