So i had a frag of zoo's that werent attached to a rock, i kinda just jammed them into a snug hole. One day i looked at my tank and they were gone i looked everywhere but nothing. Two or three weeks go buy and im cleaning the tank and out of the corner of my eye i see some orange, i found them under one of my other colonies, so i move the rock and they allmost doubled in size they didnt double in numbers but size! the tubes are twice as long and 1/3 wider. So my quesion is did they grow more cause they were so close to another colonly or just cause they were reaching for light?
