I'm not understanding your last sentence? I have 4 of them in a 30gal fuge with a sand bottom the whole system is about 110gals. do they need light? or are they alright under some macro algae?
My bad, getting late. The tank will take care of them itself.
If the tank is over 50gals (whole system), the death of the clam isn't going to affect your water parameters. In a nano, I'd be concern. With your 110gal, you're fine. The pods/worms will have a dead clam, should one die, cleaned up before you notice.
They strictly filter feed, they don't need light, and actually reduce nitrates a touch.
