This is a general care guide - it will be updated later for specific species.
Water:
Distilled, Reverse Osmosis, Rain or water with TDS under 100.
Epiphytic: Keep moist, but do not sit in deep water or they will drown. (Longifolia, Alpina, Reniformis)
Terrestrial: Can sit in water 24/7 (Sandersonii, Livida, Calycifida)
Aquatic: Obviously, submerged in water. (Inflata, Gibba)
Aqua-Terrestrial: This is not a real classification but these are ones that love water and want the water line right up to the media or even slightly over (Graminifolia, Dichotoma, Fulva)
Light:
Low to Medium light, these plants should receive around 6-10 hours of bright light, depending on the species.
When in good conditions, they will spread and flower.
Temp:
Best kept in tropical conditions (Above 65 degrees). Lower can be tolerated but growth will slow.
Most aquatic ones will go dormant in the winter, forming turions.
Media:
Epiphytes: I prefer to keep them in long fiber sphagnum, sometimes with perlite/coco husk.
Terrestrials: Usually kept in pure peat or peat+perlite.
Aquatic: No media as they float freely, but peat in the bottom of the water container.
