I have some in my tank great filter animals but I went back to get more at a stream I got these from and they destroyed the habitat. So anyone here seen these guys in the streams

Freshwater mussel's here, plenty of Asian carp which are decimating native grass carp population's.
Tried some freshwater clam's once in an aquarium ,and due to lack of green water ,and being as you surmised filter feeder's,,they soon died and fouled the water which was my first clue that they were dead, and buried somewhere in my substrate.
