SRC Member JMW Posted August 30, 2015 SRC Member Share Posted August 30, 2015 Hi guys, need some help. Saw these on LR, they fluoresce rather coolly under actinics, becoming a glowing yellow/green. But my camera cannot capture. Are hydroids known to glow under actinics? When touched, they retract into their tube & become a glowing dot Under normal lights, this is how they look like... are they really the dreaded hydroids?
