Can I save these acans?

[BrettDS]

These acans were in my old 75G tank, which had been running unattended for a while. At some point there was a bit of a rock slide and they wound up in a spot with almost no light. I thought they were goners when I moved them to my new (attended) 220G tank about a month ago, but they actually seem to be hanging on (albeit barely).

Do you think they may actually manage to recover? Is there anything I can do to help them along?

I had some that looked much worse than that which I was able to save. Just some tlc: keep parameters constant, water clean. I placed mine at almost the bottom of the tank with little to no flow. Slowly but surely they came back.

In addition to what borderreef said make sure you don't give them too much light until they're acclimated to it. Start low and work the lights brighter SLOWLY
