Cover or no cover??

I've always been under the impression that the aquarium should be open on top, to allow for better oxygenation. But all of the fish I am considering (Gobies, Firefish, etc...) apparently think the grass is greener outside the tank? What do you guys do, to prevent any of your fishies from escaping?

Yep, that's your best bet. And make sure you get the 1/4" netting, smaller fish can easily fit through the 1/2".
