I've only had them for about a year, so yes I plan to upgrade soon. I figure they'll be fine until I get out of college for sure. Anyway, I bought hornwort and put it in the tank. It is all still in tact, the fish pretty much ignore it. It has grown too I think, so it should be fine in the tank.
The Pali word metta is a multi-significant term meaning loving-kindness, friendliness, goodwill, benevolence, fellowship, amity, concord, inoffensiveness and non-violence. The Pali commentators define metta as the strong wish for the welfare and happiness of others (parahita-parasukha-kamana). http://www.accesstoinsight.org/lib/a.../wheel365.html
