It was high in the water column and doing awesome. As it started to shrink, I thought the same thing and have it to the sand bed in a low light area. --- Also, unfortunatly, I don't have a magnesium test kit - maybe i'll have RCA do a test for me. All other water params are fine and my other acan is doing great.

Are you target feeding ur acans. Do you any fish that might be picking on it?

I would only target feed them occasionally with Brine Shrimp. After I noticed the declining size, I attempted to target feed again but it didn't seem to respond well. I do have a Flame Angel, but of all the things he grazes on he never touches the acans, and they have co-existed for 6 months before this recent event.
