I was not trying to be a party pooper with the leave it alone comment but I was dead serious. After surfing these forums for sometime I've noticed people are quick to jump to the "feed more" bit without knowing what they are talking about just regurgitating what they read 100 times before. Then someone ends up feeding too much to soon and creates s totally different problem and then the real games begin.
If your tank is not being fed enough then certainly upping the feeding slightly can help. But feeding the tank just to make a new coral happy is not a good idea if everything else is ok.
Also keep in mind it can take a month or more for a new addition to settle in, the same amount of time for your increased feeding to show any significant effect, so what did it, the feeding, or did it just need time.
You have to be extra careful especially with nanos that you don't overdo it. They can go downhill relatively quickly.
Bottom line is tread with caution with acros. Realize changes take time and anything you notice overnight is all on your head, lol!!
