    Welcome to our Website, Our Pride and Joy!

    We would like to extend our heartfelt thanks to our beloved visitors and customers. Our goal in the beginning was to bring unique, rare products and new aquarium ideas into the market. And yet, we did! It was 4 awesome years of journey with you guys, and we are so grateful in having all of you. We grew and achieved a lot of things, collected some nice breed rare fishes, mosses, plants, snails, shrimps, ultra-rare shrimps, and so many other aquatic collectibles, and that made us Unique – because of YOU. Without you, our business is nothing today. So, we think this is the best time to give more back to YOU – our good clients, friends and partners! We have TWO Programs for you, it is just a start but we are trying to improve the process so it will be easier for everyone in the future.
