Top/hood/canopy question

[mrs. crabtree]

Have a 72 bow, not set up. Will the standard glass and plastic top work when tank is running? Or will it need to be "open" for air exchange (thus requiring a canopy?)? I have read about many species jumping out.

if you want it opened but are worried about jumping fish then use eggcrate for the top...
