do i really need computer fans for my terrarium? whats another way to have air currculation with a sealed terrarium? please let me know...thanks guys!

i dont think u need it, unless u have a big terrarium.
What you shoud do,is have holes put into the top of the terraium, or if it has a plexi glass cover, cut of a corner, so air can circulate a bit.
hope this has help,

Convection venting should do fine for a larger terrarium. I would want some smaller fan to pull air in or out however.

you can do like i do, don't have a glass cover that restricts light, and then have an external humidifier to pump vapor into the terrarium. it goes through a gallon of water every 3 days
