I am posting this query for my husband (I know it's been awhile since I've been here). His cats came down with ick. He removed them from the ray pond and quarantined the cats for treatment. A few days later noticed that some of the rays have ick. We know this is rather rare but was hoping for some solid advice on how to deal with this. We know how sensitive the rays are to the typical ick medicine (which is why the cats were removed to be treated). He was thinking of temporarily raising the temp and possible the salinity but wanted to know if anyone has had to deal with this with their rays and had a successful outcome.
