ok so I was at the nursery the other day and they had fresh water clams (don't know if they were a native species or not) for sale. I know they act as filters and I was wondering if anyone has added them to their pond?
I had fresh water clams in my pond one year.That's when the raccoons discovered my pond.Now they wait for the goldfish to grow to a good meal size and devour them. I would never put them in the pond again.
i don't know. i don't use a pump in my lily buckets. i guess the microscopic babies can float into them. however, they seem happy in the kitty litter bottom. i think they would prefer to be in some type of medium.
