I had a bulb actually get shaken loose and go out undetected for several weeks. Did a total mh/actinic bulb change, but coral was NOT happy with the situation, plus I had just slightly reoriented the hammer to putty it down. Both circumstances are annoying to head-type euphyllias, and a popped head is not unusual as a reaction.
On this occasion I figured maybe the dying bulb had set up the 10000k light to be just way stronger than the coral could accept, so I left the tank totally under blues for two days, then ran the mh about 2 hours, next day 3 hrs, etc....
Water's as per my sig line. The coral had reached the hanging-down-in-a-ribbon stage. Then it stopped instead of bailing, and apparently shed the part that was hanging, but the part still hanging to the skeleton has reformed as a smaller head, next to its larger sister-heads.
Never seen it do that before. I've had frog heads regrow skeleton if sheltered in a glass bowl---takes a few months. I've had hammer bud through the branches and made tiny heads.
But this is the first to reverse a 'bailout' in mid-action.
