I visited this store with Laif Demason this past Friday. While it is a little difficult to get to at the moment due to construction (should be wrapped up in a couple of weeks) I was pleasantly surprised at the amount of cichlids they had in stock. They have a number of sizes from small to show size.
We talked to the owner, and apparently they concentrate on koi during the warm months, and switch over to tropical fish during the winter. Prices were moderate to high, but everything looked healthy and the store was clean and in good shape.
I don't know their hours, so I would call first before heading out.
I also was told that on Fridays, they have a buy two get one free special.
