What is the most you would ever pay for a fish?

When I first started my saltwater tank, I didn't worry about the cost of the fish too much. I bought what was compatible for my tank and my fish, regardless of price. Then, I had an $80 fish die within three days of putting it in the tank. I was devastated, not only because of the fish but also because I lost $80.

Now I have a limit of around $50. If a fish is considered difficult to care for, then I won't spend more than $20. As much as I would love to have a rare tang or something amazing, I don't want to take the chance of losing a lot of money.

Do you have a limit for what you'll spend on a fish?
