I agree with journey here, bristle worms are normal and so are mantis shrimp.
Me personally, I think it is an easy way out for your maintenance guy, there are a few scenarios here:
1. - "oh ya you have high nitrates because of the rocks, not because of my shotty workmanship"
2. - maybe he doesn't know why the nitrates are going up, he can't get them under control so he blames it on something else.
3. - worse yet, maybe they aren't that bad (do you know the exact numbers and have seen him test, test yourself?) and he's selling you product to reduce your 'high nitrates'. Just some things to think about.
Me personally, i would have just been straight with you and said "you have abnormally high nitrates, water changes should take care of them, if not we will test other routes like testing for ammonia or nitrites to see if there is something dying, or possibly overstocks / lack of filtration." I wouldn't give you the bs of its because the rocks are from a bad area. Some people would kill to get the hitch hickers you got.
Just my 2 cents...
I actually contacted him because of the high nitrates. I changed LFS around the time I was having the problem. He told me there wasn't really a product that worked to reduce nitrates, that I would just have to keep doing water changes. He said that the rock absorbs pollutants like nitrate and when placed in good water it releases into the water. You have to keep doing water changes to get it out.
He used to be a manager at my current LFS for a number of years. He said that he used to see the hitch hickers a lot when collecting Florida live rock was legal. He said the small fish stores, like the one I used to go to, often go to a particular spot to collect the live rock. He said that one of two things happened.
1. It was collected illegally
2. It is extremely old rock that has been in someone else's tank.
Given that it had a mantis shrimp, he was sure it was the first one.
I do see the point that I would never be able to prove that the LFS is the one that collected the rock. Even if I could prove it came from Biscayne Bay. Oh well, it just irritates me that I was such a fool. Live and learn I guess.
