The razor clams are notable for their elongated bivalves. Telltale signs of trouble include: the clam shell opening wide, sudden ammonia spikes, deaths of tank mates, and tank water getting cloudy or developing a foul smell. If the water current is adequate, Freshwater Clams will be better able to filter enough edible material to stay healthy. Freshwater drum, Aplodinotus grunniens, could be an effective control of Corbicula, but these animals are not available for pond stocking. Clams have a heart, parts of a digestive system, and a circulatory system. The clams feed basically on plankton, which they ingest through the filtration of the water. Live aquarium plants continuously shed edible plant matter into the water column. They inhabit muddy and sandy bottoms of bays and estuaries. As a result, they tend to engage in more locomotion and feeding at night. Look for Freshwater Clam shells that appear thick with a ridged texture on the exterior. In defense the freshwater mussel "clams up" or pulls in its foot and siphons and locks shut, using two stong adductor muscles. Most freshwater clams eat only phytoplankton, which are microscopic plants that float in the water column. Freshwater Clams can also do well with snails such as Nerite Snails, Mystery Snails, Gold Inca Snails, Ivory Snails, Trumpet Snails, Japanese Trapdoor Snails, Rabbit Snails and Red Ramshorn Snails. I only gather from wild streams that are clear. Freshwater bivalves are one kind of freshwater molluscs, along with freshwater snails.They are bivalves which live in freshwater, as opposed to saltwater, the main habitat type for bivalves. Ammonia and Nitrites should be 0 ppm, and Nitrate levels should be kept in check with regular partial water changes. Where Do Clams Fit in the Animal Food Chain? Clams are very popular as seafood dishes due to its light taste and perfect pairing with other dishes and ingredients such as cheese, pasta, rice, soups, and so much more. If the water current is inadequate, Freshwater Clams may be unable to filter enough edible matter to survive, even if the water holds a lot of food. Soft shell clam is a suspension feeder, typically consuming a diet of zooplankton, phytoplankton, benthic diatoms, and dissolved organic materials. Clams extend their siphons or “necks” to take in water for oxygen and food. Some species are known to live for over 100 years. by being called "Corbicula fluminata"). Even when they react to the light, they proceed to close their shells. https://www.bioexplorer.net/what-do-clams-eat.html/, Top 25 Integumentary System Facts (Skin Fun Facts), Top 10 BEST Colleges For Nutrition and Dietetics, Best Colleges For Environmental Engineering, The 25 Most Notable Biology Discoveries of All Times. The critical differences between clams and oysters are that the shell of a clam is smooth with no ridges and flashy while an oyster has a sturdy and hard outer shell. Corbicula fluminea is a species of freshwater clam, an aquatic bivalve mollusk in the family Cyrenidae. Freshwater mussels, freshwater bivalves, and marine bivalves fall under the category of clams. Locomotion reduces with age meaning as a clam gets older, it moves less, which implies lower activity and thus reduced food consumption. Freshwater mussels may also be threatened by changes in fish species composition, dams that limit passage of diadromous fish species, and the potential spread of invasive non-native species like zebra mussels. Clams eat through a process referred to as filter-feeding. This does not mean that the tank cannot be “aesthetically clean”, it simply means that aquarium water needs to contain sufficient levels of edible matter for the clam to eat. First of all, clams are not just one thing. Maybe it’s due to the shift in water parameters between the display tank and the home tank, the stress of being transported, hunger or other factors. Also, be cautious with plant fertilizers. They have two shells connected by a hinge-like ligament.

An Asian Gold Clam will spend most of its time partially buried in fine substrate on the tank bottom. Amphibious, muscular river otters swim gracefully and quickly underwater to catch prey, and they can run on land. Note regarding overstocking: Its important to be mindful that keeping Freshwater Clams is like keeping other inhabitants in a tank. Clams display diverse activity. by being called "Corbicula fluminata"). Zooplankton, phytoplankton, benthic diatoms, and dissolved organic materials. Discard any open or chipped mussels. Florida’s freshwater mussels and clams are also an important food source for many fish, birds and mammals. C. fluminea is often confused with Corbicula fluminalis due to the two species' similar color and texture. If you are going to eat unshucked clams raw, be sure to serve them cold, so the shells are easier to open. In some cases the clams may be a larger. Fish like to eat them, and so do shorebirds, which sometimes break them open by dropping them onto boulders from a great height. Bacteria and decomposing organic materials. If treating the aquarium with medication containing copper, move the Freshwater Clam to another aquarium. If you live (or are vacationing) near the coast, check with your state’s fish and wildlife department to learn the location, season, and types of clams legal to gather there. Actually you shouldn't eat fresh water clams they are known to have what I think is called a Fluke. They hide under the bottom surface of the water they live in. For instance, giant clams often display nocturnal activity. What Do Clams Eat? A grouping of a few small heavily feeding clams can clear the water in a 5-gallon aquarium within hours. Some hobbyists think Freshwater Clams are easy to care for and are interesting pets to keep. They don’t eat all … Both clams and oysters have the "poop" in them that someone mentioned, but freshwater mussels have far less, and it's barely noticeable; so I do eat all the mussel that's inside the shell. To take care of a live freshwater clam, place it in an aquarium with about 4 inches of a sandy substrate. The Asiatic clam is commonly found in wide distribution in Asia, South and North America, some areas of Africa, and Europe. Freshwater Clams are filter feeders subsisting on a diet of tiny bits of floating edible matter in the water column. River otters possess long, muscular bodies suited to their life on both land and in water. Crabs are mostly omnivorous and their perfect diet includes a balance between animal and plant food. The term ‘clams’ is a general one that is used to refer to all species of bivalve molluscs like oysters and mussels. Their toes are webbed, they have short legs and they boast a tapered tail ranging up to 15 inches long. Though they are filter feeders these creatures act more like animals rather than plants. This tail serves to propel the otters through water. Many mammals, including sea mammals, are regular eaters of clams.
