Nothing has changed. The water temp is 76.7. No other corals are touching it. It under power compacts and leds. 29 biocube setup.
Sounds like it is loosing its zooxanthelae. It might be getting too much light. You might try moving to a more shaded area of the tank. Have you changed out lights recently?
My thoughts exactly Jason. If it was stringy stuff coming from a coral's mouth that is bad. With that said, that Lobo looks pretty healthy.
