Brown stuff coming out of my clam?

[drouner]

I noticed twice within the last few hours that my dersesa is expelling a thin line of brown stuff. The clam is not open all the way, almost shut.

Anybody know what it is or is going on?

This is a normal expulsion of waste or possibly some zooxanthellae. Make sure it doesn't constantly happen with the clam bleaching. If so, get a hold of water conditions, your clam doesn't like something.
