Plus 1 for pickles answer. Lol!!!
hehe. I won't speculate (publicly) what yours is going to cost.
Just to put it in perspective though, who here would spend 1 month's income on their tank?
Take Larry Ellison for example, just one of his holdings pays him over $1.5 million per day in dividends. On top of that he has many other sources of income. So just off that source, 1 month's income is about $45 million. If he were to build a fish tank, I imagine it would cost well into the 7 figures and he wouldn't notice it at all. On top of that, his net worth is along the order of 45,000 millions, so even if he dipped into savings a bit, who would notice?
Who wouldn't spend 7 figures on a tank in that situation?
