Open topped aquaria:

Easy access
Elegant simplicity
Potential for emersed driftwood designs and emersed plant growth
Does not trap heat in the system in the summer therefore is cooler

Not suitable for flying fish ;-)
Not suitable with young unruly children about ;-)
Allows for increased evaporation and requires frequent top ups
Best with suspended light source

Don't forget..Not suitable with unruly pets about

The cats sure love sleeping on top of the canopy though!

Cats crave warmth. If you're annoyed by the fact that they are sleeping ontop of it, try getting them a bed-warmer. It's a good thing yours don't drink from your tank, too... :|
