Hard Tube Coco Worms life span????

[Fishbone13]

I was wonder'n what is the lifespan of the coco worm I have had 7 for about a little over 2 years and everything online and in books is very vauge on the lifespan. But from what I do get I'm basically live'n on borrowed time cuz I here 6 months to a year is the max. Just wonder'n if anybody has had any this long or longer, they really make the rocks come to life and i'd hate for them to start kick'n off on me. I have a 75 gallon tank and add 1 cap full of Kent marine liquid calcium once a week and they just keep get'n longer. Any info would be great. Thanks

About 2 years in captivity is what I am seeing. You should write an article if they last much longer.

That's a sad thought, that means mine should be having a mid-life crisis pretty soon. What about feather dusters, do they have better longevity?

Not sure Nick, but I think I read somewhere that feather dusters can last up to six years. I'll try to find the article and get back to you.
