Subdivision of a large tank

[bLue_reverie]

I have a 60 gallon tank that I wish to use to breed PDFs. I have had success with several species in individual 20 gallon vivariums. I am not comfortable mixing different species amongst each other as I feel it can only set back the breeding process if stress through interaction occurs.

I was thinking of subdividing the large tank into 3 portions. There are two different methods I am contemplating and perhaps some of you may offer more.

In the extreme case, I would separate the three with solid thick acrylic sheets that have some degree of heat resistance (I don't know how much of a difference it would make in managing three different temperature discrepancies since I am sure it is not full proof).
The plus I guess would be complete separation.

The minus, and it usually always is in this expensive hobby, is cost. The acrylic costs a considerable amount per square ft and then there is the process of having it fused to the original tank. While this gives me the oppurtunity to play with different environments (I've been wanting to try more arboreal frogs), that would mean separate lighting, filtering, temp/humidity control... etc...



The second alternative is using simple mesh barriers with perhaps a shared shallow water pool, therefore limiting energy to one superior filter system rather than separate smaller ones. This also means I would be limited in the environment as well since all species would have to be able to adapt to the same circumstances. And mesh limits landscaping as it does not provide a studry retaining wall which sucks due to the height of the tank and my want to go up.

Any incite or advice would help. Sorry for the length of this post.
If I can't come to a proper conclusion, I may just have to go back to boas.

What if you took Chicken wire or screen and used it to devide then landscaped it with Great stuff? you could have one water table under it all using one good filter for the water by placing the screens only down to the drainage layer.
