Yes, Guppies are obviously surface fish. Just look at the shape and angle of their mouths. You can see that they are designed specially for skimming under the surface of the water.

Yes. very much so. It usually means they are comfortable in their environment. They are also hungry. XD
There are so very many surface type fish species that it is impossible to list them all here. what are the popular species suitable for a community aquarium? The most notorius are the three genera and several species of Hatchet fish and also the Archer fish (needs to be aclimatised to fresh water). These stay very close to the surface most of the time. Others that are not quite as attached to the surface are the members of the Danio family and Guppies are also a surface fish. There are others but you should be able to find most of the ones I've mentioned at good aquarist shops.
They are not at the top of the food chain they are very close to the bottom.
A canopy is the cover that goes on top of an aquarium. Often times it will have a light built into it
no a shark can not swim without it's top fin
Danio fish like to swim on the top, and they like to swim back and forth all of the time( mine do)
A simple air driven corner filter should do the job in a tiny 5 gallon tank provided the tank contains no more than 3 guppies. The first basic rule is :- 1 inch of fish needs a minimum of 1 gallon of water. Your tank is nominally a 5 gallon tank which means when it is only filled to within an inch of the top and has gravel on the bottom, the most it will be holding will be around 3.5 to 4 gallons of water.
yes! I've tried drowing it in the sink and they swim to the top and swim around

I don't know all ten. But I'm sure that the top tree are: - Dubai Aquarium (United Arab Emirates) - Georgia Aquarium (United States of America) - Okinawa Churaumi Aquarium (Japan)
