This intricate beauty will adapt very well to low light conditions. Like all Calatheas, they don't like to dry out so water regularly, fertilise monthly and watch them grow. Calatheas can be sensitive to hard water and chlorine, so ideally try to use rain or filtered water where possible.
When watered with tap water, the edges and tips of Calathea leaves can be damaged by the chlorine and other elements found in it. Ideally use rain water or filtered water to prevent this damage though letting tap water sit out for a few days can help somewhat instead. If this isn’t the cause then very dry air can cause browning tips too, try using a pebble tray or moving your plant to a more humid room like the Kitchen or Bathroom!
