Weird wormy thing?

[Shaina Carey]

So, um...I put caribsea argonite sand in my 8 gallon and I saw these worm things? What the heck are they? I am concerned. There are 2 of them

Hmm. Aquatic pincher bugs? I would net those out immediately and place them in a QT until someone provides a proper id. They look like trouble with those maws.

I dosed with ammonia before seeing them, so they will probably die off. Pretty interesting though

Yup, really cool bugs. I have no idea, and can't remember the moniker of the folks on here, otherthan @ISpeakForTheSeas ? I think that's one of the invert experts. We shall see.

Oh, and thanks for posting an unusual bug.

Some sort of polychaete worm (bristleworm) - you can see the chaetae (the bristles) on the top side of the worm in the pic (if you look closely while zoomed in, you can see a few on the bottom too).

Some polychaetes have tails with little, tentacle-esque-looking structures on them - sometimes they're longer, sometimes (like in this case) they're shorter.

I can't tell for sure what kind you have from the pic, but my first thought would be a Syllid worm; regardless, most polychaetes are harmless/beneficial for our tanks, and I'd assume yours will be too.

I am surprised they survived being at the LFS for God knows how long in a bag. Kinda hope they survive the cycling process, lol.

There's a good chance they will:

How toxic is ammonia, really?

In the context of trying to understand why so many people believe Seachem Prime was useful for them in an elevated ammonia situation, against the data in the link below about Prime potentially doing nothing to free ammonia in seawater, the question arises, why...
