Hi I am new to the saltwater hobby. I have a had my pair of gold nugget maroon clowns for about a year now and they have seemed to be healthy up until today. My male clown if sitting on the bottom of the tank not moving, not eating and is breathing heavy. The female is very active breathing normal and eating fine so I don’t know what the problem is. I’ve been watching it for a 3 days now and am stuck. I tested my water as well and everything seems okay. If anyone has some advice or suggestions I would greatly appreciate it. Thank you.
