few questions of blixa japonica

See http://www.aquaticplantcentral.com/forumapc/plantfinder/details.php?id=123&category=genus&spec=Blyxa. Blyxa japonica will not grow emersed, and from my experience it isn't wise to try to prune it by cutting it back to 1 inch long leaves. And, I don't think it will do well at 30C, but I didn't try it at that temperature.

Thankyou!!! im going to buy another plant now
