I was wondering how one knows if their acropora is happy? I have had two now for nearly a month, and my LFS
is having 20% corals! Already picked up a blastomussa for $16 and a 17 polyp colony of large orange zoanthids for $12. Im dying to get some more acroporas while their sale is going on. (Ends saturday).
I dont want to get more if my current ones are sad. I have no idea how to judge whether or not an acropora is doing well. Would a month be enough time to know if my tank conditions suck for them?
Neither have grown one bit. The green one has its polyps out all day and night. The other, some sort of purple one that turned brown, never has its polyps out but a bit during the night. Its now turning a light purple blue rather than the solid brownish purple.
So, should I run back and get some more? Or should I wait longer to make sure I make no big mistake?
