Free Acan from LFS but need help

[Markcw]

So I visited my local FS were we help help each other with frags that I have. My recent visit I was ask to take this little unhealthy fello a Flame red Acan as the owner has tried to improve it condition but having no success due to phosphate levels in there show tank. So never owning Ancan Coral I jumped at the chance to see if I could hone my skill and brings new life back into the Corel.
So I'm now 3 weeks in and things are starting to improve and look better.

Just wondering if there is any advice or anything I can do to improve my chances of saving this Corel, at the moment I don't feed but sure it collect food from my daily feed in the tank. Placed low in the tank as they are sensitive to strong light.
I've seen how this Corel should look and there are stunning to see.

Its doing bad but not unsaveable. id feed it once a week but not too much its easy to overfeed. If you know your par id put it around 70-60 par. A healthy acan however can handle alot more if acclimated, but that should do, atleast while you attempt to heal it.
