I normally have very bad luck with houseplants, but the ones in the tanks are thriving! I think it's the heat and humidity along with having peat moss for substrate.

The structure that the tanks are on is one that I actually built for raising seedlings, so each tank has a 4 foot florescent shop light that's about 6-8 inches above a screen lid (that are covered in plastic wrap). I use natural white daylight bulbs (for home/work use) from the hardware store.
In the hisser tank the two low groundcovers in the front are ivy - 'Gold Baby' on the left and 'Francis' on the right. The tall dark green thing in the left corner is dracaena 'Janet Craig Compacta', next to that is a small pothos 'Golden' that gets trimmed weekly, in the middle there is nepthytis 'Berry Allusion' (my absolute favorite!), and the right corner is filled with more pothos 'Golden'.
I also have a planted Emperor Scorpion tank that I set up a few months before the hisser tank:
The two ivys in the front are more 'Francis' on the left and 'Mint Kolibri' on the right. In the left corner is some sort of small fern, but I have no idea what type as I bought the poor thing for a dollar as it was mostly dead and I felt sorry for it. (And oh my has it grown! I'm hoping it's not a Boston Fern.) The spider plant in the middle was my splurge - it's 'Gold Nugget' and I paid nearly $10 for it. And then even more Golden Pothos in the back right corner.
I haven't had trouble with any of these plants, though the dracaena is brand new so that remains to be seen. Pothos is the probably the easiest for a low-light tank as it grows like a weed under any condition. I started with a 4 inch pot of it in September and I'm cutting that much off nearly every month just to keep it under control! (It's also in my fiddler crab tank and I've used it for my hermit crabs though they keep destroying it.) The nephthytis has also grown a lot and still looks perfect although I'm not sure how large it'll end up getting in a year or two.
I bought the spider plant and the nephthytis at Lowes and got everything else at Walmart. (Washed extremely well for 15 minutes under running water to remove any residue and remove all the soil - I have a garbage disposal though!) I think they were all Exotic Angel Plants as that's what those stores carry, and they have a website that allows you to search by lighting conditions.

Although the information isn't perfect, it's still a start.
