They are like $5-6 a piece here. If you are looking for a few of them, ask the manager or whoever if they will give you a discount if you buy whatever amount of them (6 or more I would say). I work in LFS...I won't do it for neons or whatever, but a $9 fish sure.
The above link doesn't work. I'll skip what it does, since I don't know why exactly it's doing what it does, and it's specific to how these forums interpret html in posts.
You could probably find them cheaper online, but then you have to figure in shipping costs. That's a pretty good price for a local store, better than it is here.
