That could be but I did not handle it till heads started to die after I noticed the second head die then I moved it to a spot where the flow was a bit less. then 2 more heads died on separate nights. they always seem to die at night and no flesh left in the morning. So I have moved to a spot on the rocks where the flow is not to much and the light is not to intense as that is a no no with these corals also apparently. Now we will see what is what. looks great today no head losses. I just thought that it seemed a bit odd that the only heads that were dead were on the out side of the colony.
