Hi there. Please help if you can. I have a 60 gallon saltwater tank with two clowns and a cleaner shrimp. I came back from a trip and they were not themselves. I think they may have Ich. One was lying on the sand and the other looked to have white around his mouth. I changed the charcoal to zeolite. They seem to be a bit better. I have a quarantine tank set up already. Just wanted to get advice for treatment. I do have formalin but have never used it. Please help. I'll include some pics. The last pic is my smaller one, he wouldn't come out. The other pics are of my female. Thanks.
