I use soil in mine, in a segregated area of the tank. After a 
discussion with Gary Deutschman on the newsgroup, though, I may 
try some hydroculture plantings.

> Should the plants be in pots?

Most of my plants are directly in the substrate.  I do, however 
leave several African Violets in pots which I sink into the 
substrate.  That way I can rotate them for color.  They bloom well 
even if left in the paludarium, but there is always some 
"down-time". (usually right at a major holiday when I want the 
tank to look its best!<VBG>)

If you use bog type plants or plants that can do without soil, 
like Ivy or Philodendron, certainly.  Obviously in this instance 
you would _have_ to do without soil.

I find that if I keep the front 2-3" of my paludarium uncovered, 
there is enough air exchange, and the fron glass doesn't steam up. 
 It would depend on the types of plants you were using.  I don'r 
want it _too_ humid, because my display depends to a large extent 
on African Violets which would rot from too much humidity.

Mine, as I said, is a segregated area divided off with a piece of 
glass which runs diagonally from the fromt corner to half way 
along the rear of the tank, and is about 1/2 the height of the 

> Is lighting for a plant tank about right?

No!  You will burn the terrestrial plants!  I use 2 40W bulbs over 
my 55G paludarium. (I use 4 bulbs over an aquarium of the same 
size) This is all the terrestrial plants can take.  The water 
section is lushly planted, but I use low-light plants like Java 
Fern, Anubias and Crypts.  My paludarium is also low in dissolved 
CO2 because of a waterfall that cascades down one wall of the 

>  Any publications to reccommend?

There isn't much.  I just picked up a new TFH book on 
"Aquaterrariums" but was under-impressed.

>  Any mail order scources of plants?

I use the usuall aquatic plant sources.  For the terrestrials, I 
use mostly the grocery store!<g>

A. hastifolia has long leaves that are shaped sort of like out 
native Arrowhead.  A. gracillis, which I have most often seen sold 
as A. hastifolia in this country, has very triangular leaves, and 
is a little les sturdy and "stiff" than most Anubias. Let's see if 
I can draw them:

          A. Hastifolia              A. Gracillis

The plant that (to me) looks most like a huge 'nana' (with long 
stems) is the plant usually sold as A. caladifoila, which I 
believe is probably really A. barteri var. caladifolia.

Hope the drawings turn out OK, this is my first attempt at
