Betta fish sleep on the bottom of the tank. I've never seen one close its eyes but they will often rest on the bottom when there is no action going on around them. Betta like to be around movement. That is why we have my betta fish in our living room.

fish dont have eyelids
Fish don't get pregnant. When a male and female goldfish mate, they will swim close together and then the female will release eggs which the male will then cover in a liquid from his own body. This means that the eggs are fertilized and then they will then sink to the bottom of the tank. I suggest putting some CLEAN marbles on the bottom of the tank with the eggs because this will stop the fish trying to eat their own eggs. This works.

No, not even close! Clownfish are saltwater tropical fish that belong to the Damselfish family. Goldfish are freshwater coldwater fish that belong to the Carp family.
Your Goldfish does not sleep no goldfish in the world can sleep the main this they do is go to the bottom of the tank and do not move they are resting if there it the top and floating even with there eyes open they are ded this is not nice but all goldfish do is rest.
Nothing can travel faster than light, but highly energetic electrons come the closest. The others aren't even close.
