Ooooh a new idea for a summer project: a viewing dome above water! Have you guys seen these? Basically you anchor a perspex dome with a flange in water and suck all the air out with a wet vac so the fish can SWIM ABOVE WATER. Okay, I'm a little excited about it.
If any of you have tried it and have cautionary tales, advice or encouragement I'd love to hear from you.
The fish seem to like it as much as the humans, that is what is extra nice about the whole project.
