I've been using the Brightwell Aquatics AngeLixer for quite a while now as a food soak for my 3 angels (Majestic, Flame, Coral Beauty). I usually use it every other day as I rotate between it and a few other soaks I use for their twice daily feedings. As kevdogg said the only place I have been able to find it is ThatPetPlace, but if your LFS sells Brightwell Aquatic products maybe they will order it for you. I do order quite regularly from ThatPetPlace as they have fairly good prices and sales, even get my salt mix from them to make the $100 min for free shipping.
Hoping for a quick recovery for your angel. :D
