So, at the moment, my aquarium has a crypt, bonsai rotala, anacharis, and corkscrew val. I've been told that some of these plants won't do so well in 78 degree water, and judging by how badly that anacharis melted in my other tropical community tank after flourishing in an unheated bucket, it's probably true... Most sites list a very broad range of temperatures that a plant can tolerate, but that apparently does not mean it will thrive. So! I would greatly appreciate suggestions on easy-to-grow (ie low/medium light and low CO2) plants that can grow well in 78 degree temperature water.
