How much for fish?

[Enin]

A friend of mine recently bought 5 fish and i couldnt believe what he paid for them. So this made me wonder how much others paid for rare fish since im new to keeping. I would like to know how much is the most you have paid for the most exspensive and what fish it was. Thanks

I once bought 4 betta imbellis from Thailand for about $100.00. So $25.00/ fish.
