Water sprite requires no special care...at all. That's why it's even easier than plastic or silk plants which require you scrape algae periodically (that's a mess!).
My current tank is a 20 long with a double bulb hood (this was what I also used on my 36" long, 17" high 33 gallon tank...but I downsized tanks when I moved my tank to another room...I've been slowly downsizing tanks and tank size for a decade now). I have an aquaclear HOB filter, heater, and gravel for the substrate.
In earlier tanks (including a 29 with a single flourescent bulb), I've grown water sprite (floating), java fern (tied to wood or rocks...it eventually roots to nearly anything, but tied on with fishing line at first to keep it in place), bolbitis (an african water fern), and java moss. I've also grown some cryptocornes, but they do better with more light than the other plants I've listed.
If you want to give plants a go, my usual recommendations are watersprite floating, java fern or bolbitis tied to anything.
If I hadn't tossed a ton of the stuff when I moved tanks last month, I'd offer to mail you enough java fern, water sprite, and cryptocornes to get you started. However, what I put in the new tank isn't producing enough new growth yet for me to share.
I stayed away from live plants for years, messed with a CO2 super high light set up for about 5 years, got lazy, and moved to my low light plants. No special care, and my water quality is great...plus the fish seem to really like the real plants - better to hide in and fry survive more often with real plants (much better hiding places for fry).
I'd never go back to plastic or silk plants.
