My male swallowtail looks like it's changing, his stripes are not as dark. My question is, I thought he had popeye in one eye. But I read if it's one eye it could be an injury. I started giving him kanaplex in food and then water for 3 rounds back to the food because I don't want to kill my inverts. I can't catch him to quarantine him without tearing up my rockwork. His eye is less swollen. But still swollen. Shouldn't it have gone down by now? Still feeding him kanaplex and my other fish are eating the kanaplex in their food by default. I've been putting vitamins and garlic in the food too. My other fish and the female swallowtail are doing just fine. What could this be? He's now chasing the female again :0) and eating nori. Swims with head down still.
