First of all I'd just like to say what great forums these are! A lot of things I've been wondering have been answered just by reading around here.
My question is, what plants are these? (the tall ones, not the one in the pot)
also, they are turning yellow at the top, is this because of too much/too strong light? I have a 15w lamp on 10-12 hours a day.
Thanks in advance!
ps. I know the tank is terribly bare, I'm getting some more plants soon and the small java ferns I've got should grow a lot bigger as well.
