Yeah, I became "not a fan" of FW dips when I took a fish who was definitely stressed and fighting off disease and threw him in a carefully prepared bucket of FW, then watched him thrash his final death throes. I'm sure he was not going to make it either way, but there has to be a more dignified way to die.

I have had fish that were eating well recover from the velvet and that is/was probably your best chance. It's such a tough call how to get your best odds of success with these guys, because most literature agrees that it's best not to bother to quarantine anthias for a number of valid reasons.

I was very pleased with the three I originally acquired from Live Aquaria and know several others who have had the same experience. Highly recommend going that route for lyretail anthias. Good luck whatever you decide to do.
