I have a 37g and a 65g ordered. I keep discus and Angels. I love the planted tanks, but don't think I will get into co2, fertilizers, etc......just want a few plants for my discus.....it would be beautiful! Doesn't take much to entertain me!
Welcome, a dirt tank is always a good option if you're going low-energy. Failing that root tabs will work well. As for plants try Amazon Swords, Java Fern, Anubias, Vallis and Crypts. You may still need to dose fertz if you're only using gravel. Just use ready mixed fertz. They're no fuss and easy to use.
