African Clawed Frog breathing press?

I just filled the tank to (almost) the tippy top. My sound out is, will they still be able to breathe if there's literally this much space between the water surface and the lid?

There may be more, or even smaller number, I can't be sure because of the way the tank is constructed. Help is appreciated, 4 stars to best answer, 5 whether you provide a website forum/info page.
Why does one of my goldfish float...
Answers:    Its best to give them about an inch and a half or more. They come to the top pretty quickly. So they arent going to go to the top and stop as soon as they hit the top of the water. They will shoot up, get pretty a bit of their head out of the water, and go posterior down. Take some more water out. Itll be best for your frog.
