Whoever said Christmas cacti aren't really cacti? Of course they are! Sclumbergera truncata usually, or some hybrid with that species. Easter cacti are Hatiora gartneri or a hybrid, despite looking very similar.
No need to bother with any special watering regimens, they don't care much about drought or being moist constantly. Being sat in water for weeks isn't good for them. They're not fussy about what you grow them in either. Not moving them when they're developing buds is a good idea too. They go 'senile' as they get really old and never seem to flower as well as really big plants, so it can be advisable to start them off again as cuttings every 5-10 years. Being pot in a pot with little root room encourages flowering, which applies to Epiphyllums as well.
