If it isn't too late already, it is actually pretty sensitive to water changes. I had mine die i think three times before I finally got some that stayed alive. Acclimate it slowly just like a fish. I'd start out right away with 24/7 light. And, it will attatch itself, but you can always stick a small rock over it somewhere to help it get anchored. It will do so very fast, if it decides not to die. When I finally got it to make it through acclimation (and hard shipping), it took root in about 3 days.
