I’ve had this lyretail for several years and it has just remained female in the absence of any other anthias in the tank. Over the last few weeks I’ve noticed some dark purple splotchy patches and a couple bright purple marks on fins. I’ve circled in the photo below. She is also looking a little ragged in general and just tonight I noticed a nip out of her dorsal fin. All of her scales also seem to have a slight tinge of purple on the edges which makes me hopeful she is just going through a sexual metamorphosis. Thoughts?
