I am looking to purchase an aquarium/fish tank for my daughters room--for her 3rd birthday which is at the end of January. I haven't had a fish tank in probably 25 yrs, and have forgotten the joys (*snort*) of having such a thing...and the few times that I have briefly looked at them, they seeem to have a whole host of new kinds of fish tanks (small/self contained, etc).
I know 3 yrs old is rather young for her own tank, but there are reasons for it (too much to go into) though we are redecorating her room in a fish theme, so it would fit the decor and she LOVES fish.
So to those w/fish tanks, how big are they? How many fish do you have? Do you have a lot of things in the tank? How often do you clean it?? What are the downsides?? Please be honest....
