My newest fish, L018 gold nugget, had a $40 price tag (CD). Because I work in the store, I paid $19.99 + a trade in of a few platys.
I'm starting to really enjoy plecs, I can see myself setting up a much larger tank and spending big bucks on rare plecs in the future.
ashdavid, why do you say the money you spent on your arowana is stupid? I've seen price tags as high as $5000 and $ 10 000CD for large arowana (~8"), even smaller ones can go for $1000.
I saw a $25 000 parrot today, horses can cost tens (or hundreds) of thousands of dollars, and chihuahuas can go for $3000 or more. The way I see it, it all boils down to buying a pet, and if you love the fish it's worth it
