I've never been to this LFs (indeed, I'm not even sure where this is) but when I when I lived in Japan this summer, I went to Shinjuku Aquaforest all the time. The selection and quality of fish, plants, shrimp, and even nerites was great. Though everything is there, it's just different as far as prices are concerned. At 600 yen, I thought the price for a bunch of hemianthus micranthemoides was pretty out there. HC and Eusteralis were also really expensive compared to prices through trade here. However, I thought it was cool that I could buy a huge bunch of R. najenshan for 250 yen (on sale from a normal 350 which is still good IMO). Also you can get a lot of grade C bee shrimp for pretty damn cheap. It's just a different market.
