It sounds like your lighting situation is limiting.
Baby tears is going to probably do ok. If not shaded by other plants.
You have spider plants, pothos, agloenema, fittonia, some bromeliads, phaleonopsis orchids, calathea, anthuriums, draceana, and more or less things found in the houseplant selection of box stores. Some toxic plant list will list various plants as toxic, however none that I have mentioned carry and risk greater than pothos, which contain oxalate crystals, that many of veileds have consumed and shown no cause for concern. On that note, you might try caldiums, if your humidity is high enough. In general, the more colorful, the more light the plant will require. An eBay search will show you a fantastic array of colors of agloenema, but keep in mind, the more colorful, the more light they need to show the colors. Guzmania bromeliads will give you some pops of colors for several months. You might even try an African Violet for its blooms.
