If I had the cash I'd spend $10k on a few select fish, but not a coral. Expensive fish come from way deep (usually) and people die collecting them so I can justify the cost. Corals are shallow so I can't justify $10k.
(...and mushrooms - I'm just not a fan)
I'd pay $100 for a Bounce mushroom, but that's only because I know I could sell it and make big dough.
