You are way too optimistic. The cat would fall in the aquarium, knock over the lighting system trying to get out causing the lights to fall in the water which would cause them to short circuit electrocuting both the cat and fish and then setting your house on fire leaving youDo you have a cat? I ask because I do and we are having the same debate in our house. Alas, we will have to cover because he is just too interested. It would be sad if he ate our $8 fish, but even more sad if our $1800 cat drowned in our 180g tank. We ended up ordering an extra set of lights to compensate for the cover.
