buy yourself a small computer fan and mount it into the hood with some fine mesh below it.
have a hole drilled in on one side to acomidate a ventilation ring, like what are used in snake vivs. an internal fan would only make the air which is already in the viv circulate.

"I have always liked frogs. I like the looks of frogs, and their outlook, especially the way they get together in wet places on warm nights and sing about sex."
“If we can discover the meaning in the trilling of a frog, perhaps we may understand why it is for us not merely noise but a song of poetry and emotion".
I recently picked up one of these for free (sat on a wall outside a pub with a note in saying 'please take me!! Rude not to, I thought!). All I had to buy was the lid.
I drilled some smallish holes (think I used a no.8 or no.10 drill bit) in a couple of the top panels and siliconed some plastic mesh with fine holes that I got from the garden centre across the lid on the lip, so my fbt's can't escape through the cable exit bit. It works a treat!
