You should have waited another month to plant them. It is not easy to keep seedlings of outdoor plants indoors. I am just now started the hardiest of me seeds and many are still on the waiting list. It would be helpful if you post a picture and tell us about you set up, lights and stuff.
Well, I do bring my BRT and other tropicals inside during winter. Here in NY, temp drops easily to 30-20s and won't go over 70s till late march, early april.
As far as condition, they're place by a window + grow light (12hrs). Temperature is around 68-72. I've been trying to increase the humidity, but nothing really worked so far, and the room's humidity stays around %40-50, which I heard is not enough.
I planted around 20 seeds 2 months ago, only 5 germinated, and 4 survived. One of them seems strong, the other ones are still fairly weak. I'll get a better picture during daytime.
