Hi, everyone. First time here. Picked up a plant with bright purple/pink/almost red leaves at a plant store last week. The man at the shop said it was an indoor plant, and only needed about a cup of water a week. I've had to water it every day to keep it from wilting, but it's just not doing well. I thought I could take better care of it if I knew what kind of plant it was. I google imaged searched to no avail. I've attached an image of one of the leaves for reference.
Thank you in advance!
