I've looked around and couldn't find anything on this. Are there any health risks for a peacock eel if I install a blacklight bulb to turn on at night? Don't know if it messes with their eyesight or their day/night cycle.
"aquarium moonlights" are fine. blacklights are not. i wanted to do this and i asked my old biology professor about it and he thought it might screw up their eyesight.
