plenty of plants can handle temps in the 60's in the winter, some even in the 50's. Just grab a good plant book or look online and away you go. I set up my bowl to make it through the midwest winter and it has Japanese moss balls, nana petites, frogbit for floaters, a dwarf sag, some willow moss, and a pennywort all in 1.25 gall. Current Betta Cube. I just use black aquarium gravel. Really makes the colors pop with the LED daylight bulb. Along with a few horned nerites for algae control and fertilizer. It looks great. I would recommend getting a small clip-on or desk lamp at approximately daylight range and timer for it though. I tdon't have driftwood or rocks, just plants, but whatever catches your fancy, grab it, bc you will enjoy looking at it.
