I got 2 planted tanks a 10G and 20G. They aren't really planted my 20G long has 2 of one kind and 10G has only 1. Now I really want my tanks to be planted but im never good with plants all of them are dying (pic below ) if I need to trim it I don't know how. I'm pretty new to plans and all. I just want to start on beginner plants so any advice would help thanks!
