So swords are okay to put in a new tank? I am about to place an order. I need answers ASAP.As a planted tank newbie myself, I can only speak to what's worked well for me. Haven't tried corkscrew vals, but my jungle val has taken off and has leaves across the top of the tank. Definitely an easy plant for me. I've got an "Aflame" sword that's doing well and putting out new red leaves, so that's another easy one.
As others have pointed out, be careful with the duckweed--that stuff can easily take over if you're not careful. And don't let it get into your other tanks--all it takes is a tiny bit from a net, water siphon, whatever to infest another tank with the stuff......
