Yes they will eat clams but only if the clam is dying already. Bristleworms are unable to kill healthy clams, and are usually opportunistic feeders (like eating the dead fish in the back of the tank when/if that ever occurs).
Agreed. But they will at times irritate them by rubbing against the tissue on the underside (bysal gland). If a healthy clam is not opening for a period of time, I often find a worm or two when I turn the clam over. After removeing them the clam seems happier. Randy
So what your telling me is that it's "beneficial" to have bristleworms in your tank. My tank is barebottom though.
For some reason they have been multiplying like crazy in my tank. I must have like 20 bristleworms.There is one bristleworm that is like half inch wide and I think about 4 inches long but can't tell because part of it is under a rock. The rest of the worms are tiny compared to it.
i have a ton of them in my tank and they dont bother my 6 clams at all. if you are going bare bottom, and want to get rid of the worms or control them, i suggest you get a coral banded shrimp, most of my tangs and clowns eat them, but im not sure what fish you have. bottom line, finding a natural predator should not be a problem.
