[Not Heidi]

I have a 15 gallon Fluval aquarium. It's been running for about a year. I've wanted to plant it, but not knowing how, I waited. About three weeks ago I bought the plants and put them into the aquarium.

Within a week, the two tall ones (don't know their name) began flagging. They grew weak, and slowly turned brown. Within a few more days, they were completely brown and had wound up flat on the gravel, waving a bit with the current. I took them out. I'm very sad.

The other plants seem hardier, but most leaves have small brown sections on them.

Why have I become a plant killer? I'll appreciate any advice you can give.
