Hello everyone. I’m new to the saltwater fish world and I have this clownfish who I think might be sick. He eats great and and can be very playful with my other clownfish but over the past couple of days I’ve noticed that he tends to stay close to the bottom of the tank gasping for air and looks more pale than normal. He still plays with the other clownfish only he looks more like he’s trying to hide from her than play. I checked my water parameters and everything says it’s good. I’ve googled what it could be but there are so many different possibilities I’m not sure what it is or how to even try to treat him, any help would be greatly appreciated.
