“The red glow is likely a form of private communication or an attraction signal, Nico Michiels said, though he doesn’t have clear proof yet. Because the light is coming from the fish themselves and not filtering down from the surface, the red glow remains visible at depth and is easily seen at close distances only.”
“Fluorescence occurs when light is absorbed at one wavelength and then re-emitted at another nearly immediately. In the case of the red fluorescence, these fish absorb light at blue-green wavelengths and re-emit it at red.”

Jumping guard
A jumping guard prevents (nocturnal) fish from jumping out.
Wrasses, blennies, hawkfishs and gobies jump out of an unprotected tank in fright if their night rest is disturbed, unfortunately these jumpers are found dried up in the morning on carpets, glass edges or later behind the tank.

A small night light also helps, as it provides the fish with a means of orientation in the dark!
