Hey everyone, I am looking to start a small 10g aquarium for my night stand. I plan to put a school of tetras and some snails in it. I was doing some research and it says that tetras like planted tanks. I was wondering if it is ok to put a few Jungle Val in a 10 gallon tank. I know that they get long, but I figured if I trim them more often I could make it work. If you don't believe this would work could you recomend some other easy to care for background plants. I have low light so I am keeping that in mind. One more question, do I need a CO2 injector for this?
