yo daddyo,
my advice would be forget about the "tank" for now.
most CPs grow much better outdoors in full sunlight.
(and they catch their own bugs that way too!)
start with Venus Fly Traps and/or Sarracenia (North Americian Pitcher Plants)
plant them in pots of pure peat, or pure long fiber spagnum.
(there are other mixes, but these are the simplest to get started with)
if you buy peat, make sure it has NO fertilizer added.
put the pots in trays of water outdoors where they get full sunlight.
use only rain water or distilled water to keep the trays filled.
thats it!
thats the
basic basics!
there is plenty more to learn besides that!
but you could do your first CP season with that knowledge alone.
I second the idea of buying "the savage garden" book..
as you learn how to grow Sarracenia and VFT's, you can graduate to the more "difficult" species like Nepenthes..
and you might be able to use the tank for those!
but my advice would be to start very simple..
start with VFT's or sarracenia outdoors..
