I have 5 ocellaris clownfish. 4 orange and 1 black. My little black clown has gotten some weird looking stuff on his face. Almost like his face is bubbly looking?? And it’s turning white. It’s been like that for 2 days. My dad just said to watch him and make sure the others don’t get the same thing. We don’t have a quarantine tank yet but we are trying to get one. We have Paraguard though. But I’ve heard people say not to put it in the main tank because it can mess up your filter. I could not get a good picture because he wouldn’t stay still but I’ll attach a couple. What do I do?? Is he okay??
