Any suggestions about what I should do here? This coral is 15 weeks old. It has done very well during that period and has added new growth.
The branch at the bottom left first appeared bleached out yesterday.
The branch at the middle left and the spot on the middle of the trunk appeared bleached out today.
Otherwise, this coral and the others in the tank (some 3 years old) appear normal. No new corals, fish, lighting, food changes since this and 4 other corals (all still doing fine) were added in December.
I'm concerned the bleaching may continue. Any suggestions about what to look for, what to do?
Thanks
