Not to be mean or rude but I think you would have better luck with houseplants if you would research there needs, a prayer plant is actually difficult to grow.... it isn't for beginners. because its in the calathia group anything calathia is going to need a terrium, or be covered/.
they have a dislike for lack of humidity, need warmth.... lots of water,ect.
I have better luck with potho's, dracenia, some gingers,ect. they are more forgiving of mistakes and can tolerate average homes better then a prayer plant.
