I like the aquariums, I really do, they add a hint of life to a home and that to me is a very nice touch I am happy they exist.

I do not however like the 1/estate restriction. I realize this games housing is highly restrictive in every aspect .. but would love to be able to add at least 1/floor.

Would also like the ability to alter the lighting intensity of the aquarium and the lighting color I have added my own lighting but it has minimal results, would like some LED style lighting designed specifically for the aquariums. (intense settlings, color changing etc)

I agree with the op, many more fish would be cool.
