Feeding Freshwater Clams
The Care of Freshwater Clams
Next to toxic aquarium water (ammonia and the like), the feeding of freshwater clams has been their demise in aquarium culture. Many unsuspecting people are told their clams do not require food and believing the “experts” innocent fish keepers wake up weeks later to find their clams dead. They had starved to death.
If the clams are buried in the substrate and in a smaller tank (large too, depending on the number of clams), they destroy the waters’ parameters quickly, killing fish and invertebrates.
This recipe is one I am successfully feeding my clams. They are growing noticeably when I measure them each month. Their shells are hard and remain intact.
Use this at your own risk, as I will not be held responsible for any undesirable outcome that may occur.
All of the ingredients are pureed in the clams’ aquarium water and frozen into ice cubes for long-term storage. The fish and larger invertebrates eat the leftover bits. These measurements are not exact. I feed three or more times a week.
Clam Diet Recipe
Beef Liver or
Beef Heart or
Fish with Roe (best)
Beef Blood (drippings from beef package)
1 tsp Cod Liver Oil
¼ tsp Yeast
In addition to this diet, I target feed my clams with these:
¼ to 1 tsp Organic Carrot Juice (they love this)
Organic Spirulina Powder
¼ o 1 tsp Milk
They will also eat algae from my pond and leftover (tiny) bits of fish flakes when available.
This is a well-aged setup. Overall, the community tank and its inhabitants are healthy, active and doing well. The tank has biological filtration, live plants and sand-sediment as a substrate. All of the chemical readings are in order as well. I test frequently before and after feeding the tank just to make sure it can handle the bio-load of suspended food. The readings do not spike.
Like I said, it works for us and Use at Your Own Risk.

I did some research and it said spirulina contains copper, which I thought was bad for clams.

How much meat and water do you add to the mixture? Also, what amount would you regamend putting in the tank for 3 small clams?

I need to expand on this article to make it read clearer. The milk can be mixed in with food as its being pureed. I'll make a note to update this article this week. Thank you for your comments guys!!!!
