tetra

I am new to the tank, bit was really excited to start learning more about my fish and the tank. My fiance got me a small tank with two tetras and one green danio. My danio would swim about the tank, never just chillin. When I came home from work the two tetras where dead and the danio was fine...

I have a 10 gallon tank (which I realize is quite small); that I intend on turning into a planted aquarium. I want to add some fish to it as well but with the tank being so small and the plants taking up a lot of room I'm concerned about overstocking. I don't have any equipment for the tank yet...
