Clever Dispar anthias learned to use the light from refugium to hunt pods at night

[Tripod1404]

There is a 30min delay between the shut off of tank lights and refugium light. During that period pods in my tank start to swim and get attracted to the only light source in tank. Dispar learned to use this light to her advantage to hunt them.

Here is a link to that video

I do not know if you guys ever witnessed it or if this behavior is natural. Maybe they do hunt plankton during full moon and this light somehow induce that behavior. Good to know sometime eats all that pod that swarm around my tank during night
