Fish, or goldfish anyway, never sleep. Well, they don't sleep the way we do anyway. They go into a sort of relaxed mode where they slow down but they are instantly ready to swim away if any danger appears.
me, being as thick as i am, dont know what nocturnal means. But goldfih are awake in the day, and sleep at night. Make sure u turn tank lights/room lights off because they dont have eyelids and cant sleep aswel in the lightThat answer your question? :DNo, goldfish are diurnal.
they go into a resting phase which is a phase where they use less energy

I heard this from someone. Though it is unbelievable, goldfish, if tooken care of well, can live up to 25 years! I have heard of a goldfish that lived 50 years! I cannot imagine my little one inch goldfish living for THAT long. =)
