Video camera for aquariums

I am looking to find a better camera to take videos of the aquariums I work on. The point and shoot camera I have now has no auto focus and just about everything looks white no matter what settings I use. I need it to be at least 720p, but I am not willing to pay twice as much to go any higher. Doesn’t need to be water resistant or anything fancy.

Thoughts?

Suggestions?

Which model camera are you using now? So as i don’t go out and buy one…
