Just got this clownfish today and she looked perfectly healthy in the store but once I got her home and started to float her I noticed a filmy white coating all over her. This was really only visible under my blue light. I did a freshwater dip but there was no visible change. She’s very alert and active with a good appetite and is surprisingly relaxed considering the circumstances. I’m going to quarantine her and treat with copper but I’m just not positive if it’s ich or something else.
