Todd, I think you have a really healthy Corbicula in your tank. He's grown a
lot recently, from the look of his growth rings, and if you look closely you
see that the tassellated edge of the mantle is protruding out along the edge
on the left. Interesting, their exact effect on native mussels is still
unclear. Zebra mussels have direct, immediate negative effects on native
mussels. But Corbicula may be more neutral in its effects. A graduate
student of mine tried to find any literature on the negative effects of
Corbicula and really couldn't. If anyone knows of any, I'd be curious to
find it and read it.
