Two hides, water, cypress substrate -- so far so good! What are you looking at as far as temperatures and humidity are concerned? And do you have an under-tank heater, or is the lamp your heat source?

If you've read around here a bit you've likely seen folks mention that screen-topped tanks can be challenging as far as maintaining proper humidity is concerned -- if your humidity is running lower than 50-60%, you will want to explore some options to raise those levels. Also, another thing you've likely read on the boards is that some small BPs find a larger tank a bit overwhelming. I see all the plants you have in which I've seen referenced as a good way to make a baby snake feel more "snug" and less lost.

I'll hush for now and let the more experienced folks chime in, because my experience with BPs is admittedly limited

Here's a great thread on setting up a BP tank enclosure, if you haven't already seen it: The jfreels glass tank setup w/pics.
