Does anyone have info on clams? I have a 120 gal. with sand substrate.What do they get along with or not get along with ?what do they eat? So on and so on.
If you like watching paint dry then you'll love keeping freshwater clams.
Seriously, though. They filter out fine particulate matter from the water column for food. It can be hard to keep them well fed over the long term. If they die, how will you know? Other than the ammonia spike?
