Frequently asked questions
Will a clam clear up my cloudy water?
Yes — that is real; a few clams can visibly polish green or cloudy water. The catch is what happens afterward: once the water is clear there is nothing left to eat, and the clam begins starving. If you want clear water permanently, fix the cause; keep clams only if you are willing to feed them.
How do I know if my clam is alive?
A live clam buried in sand shows two small siphon openings and reacts by closing when touched; a dead one gapes open and does not respond. Check every few days — a dead clam decomposing in the substrate can spike ammonia fast in a small tank. A clam that sits on the surface unburied for days is usually in trouble.
What do I actually feed a freshwater clam?
Suspended micro-foods: live or bottled phytoplankton, powdered fry/filter-feeder foods, or finely crushed flake swirled into the water near the clam two to four times a week. Turning the filter off for 20–30 minutes while feeding keeps the food in the water column where the clam can take it.
