Firstly, there is no such thing as an Indoor Plant girls. One must remember all life on earth need the sun to sustain healthy life, including us mere mortals.
Secondly, the plant you refer to from the "Aloe" family do not grow well ina pot, let a lone indoors. What you may like to do is check how large the plant is and make sure you do not bury too much of it under the soil as they have a tendacy to rot when over watered. Then, when you feel the plant looks like it has room to grow down as well as sideways, then your ready to water it. Mind, water only once a week and allways leave the plant in a postition where you know it will recieve optumion Sun light for as long as possible every day. Of course, it would be better if you could leave it on your balcany (if you have one?) all day in sun or when you are home on weekends. I hope this helps mate, cheers
