Are goldfish Diurnal or Nocturnal?
Hello! I have goldfish in my pond and everytime I watch them at night they are always swimming around and eating algae. I do feed them well during the day but I just never see them resting like the white cloud minnows do at night.
I was just curious if anyone has ever seen their fish/goldfish behave like this.
P.S. they seem to swim about at night as gracefully as if the sun was out.
Could they possibly be nocturnal as well?
