Acan seems to be having some trouble

[fabbss]

This my first acan, I am an sps guy. But I reall like scans and their color. I just bought a few heads from my LFS these were under LEDs and I am running 120 1w LEDs on my 25g cube. The new acans are on the sandbed in the center of the tank. They don't seem to be as puffed up and it looks like some tissue is being lost. When I feed the tank they have good poly extension. Could it be the lights? I also have a lot of Astraea stars in my tank, could they be attacking the acans? Thanks

I forgot to mention parameters are normal, great polyp extension on sps and other corals

if they are new to the tank it takes them time to adjust .if the feeders are not out all the time there is no need to worry they just dont detect any food.givem time i find acans are the easiest of all the corals if you feed them.

If you are already seeing what looks like tissue loss, I would definitely shade them and feed them if they will take the food.
