I was interested in changing out the decorations in one of my boys' tanks with live plants lately, but I know nothing of what they really NEED as far as plants go. So I have a few questions:
Is a 3 gallon tank even enough to put all live plants in?
Is an artificial sand substrate able to sustain live plants? Or do I need to get some kind of soil?
Will LED lights provide enough light to keep the plants alive?
Are there any other things (like rocks, driftwood, etc.) That need to go into a planted tank?
What are good plants for beginners?
I'm completely new at this and never actually have had a planted tank at all, so any advice and information helps!
