I've had this duncan for about 6 months. Single head turned into 8 heads, normal growth, was always fully extended and swaying. For the past week its been like this. All my other lps are thriving. Even my montipora is growing well. Is this normal for duncans during skeletal growth? Could my coral beauty be causing this? Parameters are all in check. And even if they wherent you would suspect the sps to be the first to show signs.
