STOCKING THE AQUARIUM

Now that the aquarium has been set up properly, the time has come to think about the living creatures we are going to put into it. As it stands now the rocks and the plants make an underwater aquascape. But it is static aquascape, nothing moves in it.
Before setting out to buy the fishes, however, it would be as well if we knew something about the different parts of a fish and how we can distinguish a live bearer, that is a fish that does not lay lay eggs, from an egg layer.
