I had some out in my pond, then brought it inside for the winter. It needs to adapt you your tank, so you might get some roots falling off and causing a mess at first. Here is what has worked for me;
Little to no current - A sponge filter at most, HOBs will screw it up - especially when the water level drops
Little humidity. I had this in a tank with a hood and it had all kinds of fungus, yellow leaves, stunted growth.
Keep it a little further away from light source. I use CFL bulbs, and if I give it a few inches it's golden. If you have anything that puts off a bit of heat, give it more room.
I have put it in all my tanks. In my fry tank with the sponge filter, the water lettuce is doing the best. I also put it in my filterless beta 10g, but it was taking over, lol.
A few rules, but once everything is set up, it's a great plant.
