Hello I am 14 and a newbie here and will I am in the prossece of getting a ten gallon aquarium setup I have a small water garden in my back yard with 2 common and 3 comet goldfish. Well while I am setting up the water garden I need to get some submerged plants in the spring well I am planning to get some fresh water clams in a cascade going into the pond. Well can you tell me how to take care of freshwater clams and how to breed them. Thank you for your time and I look forward to posting at this site again.
