Hey, I am new to R2R and i have had a 29 gallon reef tank up and running for at a month and a half. Yesterday i fed my fish and some of the food got caught in the tentacles of my trumpet coral. It ate the food but then a few minutes later the head of the coral doubled in size. Later it shrank back to normal size again. What does this mean?
