I know what you mean about the fluids, my parents were literally force feeding, or should it be force drinking, me with huge glasses of water, and i just wasnt thirsty, no fun.
lol at the childrens farm, i'd never thought of it like that, i'll have to point it out next time i'm in work!
The tank measures 100x40x40 cm, approx 39x15x15 inches i think. I was a really great bargain, i dont think the guy really wanted to sell itme that cheap but he had to honor the ebay rules, not that i minded
The lot he sold me included the tank and hood, an interpet master test kit, two siphons/gravel vacs, two tubs of in-date food and about five bottles of water treaments. Oh and i nearly forgot, there was also an automatic feeder in there that is specially designed to fit in the hood of this tank, and the best bit is that the feeder box still had a price ticket of £19.99 on it!! I got the whole lot for only £16, the guy made such a loss!
As for the shells I do have a load more but i didnt put them in as i wasnt sure how many they needed but now you've said i'll go throw another couple of handfuls in.
I think when i've got my rocks i'm going to do something similar to your tank, with rocks on one side and shells on the other, this decoration was just temporary really so i could see how it looked.
