Bristle worm infestation?

[Todd]

Snappy - 33 Gallon tank with 2 x Maroon Clown, 1 x Coral Beauty, 1 x Purple Pseudochromi, Lots of crabs (blue and scarlet hermits), cleaner shrimp, and a dwindling snail population.

When I plucked a worm out of the filter I put him into the display tank to see what would happen and he was quickly munched on by the maroon clown, but I am still unsure of how he would have gotten into the filter in the first place - free floating larval stage?

I know I have at least one larger worm still in the tank, and I have removed one medium sized one too. None of my fish are big enough to get them, but definitely could handle the smaller ones.

Bev - I usually clean my aquaclear foam at least weekly, often more then that. But this time it may have been 10-12 days, as I also found more large pods then usual. Haven't had a chance to look up the worm yet, will do that tomorrow.

Gary - its possible that I am overfeeding, I have an auto feeder that puts a small amount of flake in twice daily. This is snapped up right away. I also feed frozen (blood worms and mystis) once every two days. I haven't checked my chemistry for a little while - will do that tomorrow

AC - Wondering if leaving them in will lead to a population explosion. Have you found that they stay about the same? I already have an aiptasia epidemic on my hands....
