night light in reef

[Dresden]

i'm gonna though out an opinion which has no research behind it.

My guess would be lunar light isn't the factor, its gravity or tides or both. Maybe even magnetic fields? Too many factors, we know many animals use the magnetic field to migrate, probably the same /w mating and the tides. Could try having some fun with a large magnet, powered subwoofer or something surround the tank and look for any effects.

I know anenomies split alot aftrer a full moon, but how would it tell from inside unless..

A) its not due to light but someother effect it can feel
or
B) its internal clock is so accurate it can predict the full moon(like those under ground animals that only come up to breed once every 7 years same day on the dot.)

Theorizing is fun weeeeeeeeeeeeeeeeeeeeeeeeeeee
