what's minimum light requirement for it?masterswimmer said:Bobby, that lighting is very inadequate for that clam. Unfortunately it won't survive under those conditions. You might get a month or two out of it, and everything will look fine, but the clam will die from within and overnight you'll see it waste away to nothing.
I'm very sorry to have to be the bearer of bad news. It's important to research the needs of these beautiful animals before you put them in your tank.
