Some people prefer fish as their pet and some just enjoy the company with fishes as their hobby. If you love fish and different aquatic creature then you would want to check out ARDB.com as an Aquatic Reference Database that has plenty of resources on the aquarium hobby. Feel free to visit the Aquarium Forums and Tropical Fish care. The forum is dedicated to tropical fish care in freshwater and saltwater fish tanks. It is an online aquatic community with forums dedicated to the hobby.
I just want to share these two different underwater creature taken in different place. The first photo was taken in Japan over 6 years ago. The picture is a bit blurred because I only take this in my hard copy photo. Feeling nostalgia.
Picture below was taken in Pittsburgh Zoo last year. Just like dolphin, this one also swim with grace.
