I found this guy on a rock early this morning. I have others that look similar, reddish, but generally body is in the sand with hairlike tentacles sticking out. I was told those are spaghetti worms. This one was thin about ½” long with tentacles. Are spaghetti worms known to crawl on rocks or is this a fireworm? Thanks

Thanks for the quick reply. ChatGPT sent me down the fireworm spiral. lol.
I tried to discuss Ai with some younger men yesterday and they couldn't say enough good things about it. They also admitted its not perfect, and come to think of it, I am not either. Maybe I am Ai, V.1?

It’s a huge timesaver for me but use with caution. Review everything. Hence my post here with real people to check.

AI is fascinating. I dont rely on it to answer any real life questions or issues its usually wrong on that stuff. From what I've seen it cant math either, its actually worse than me. I have used it to help build fictional worlds and characters though. It's neat, tell it what you want to see and it does its best (pretty good actually) to give you what you want and then tell it to tweak what you dont like and it gets even better. That is its good and bad points all at the same time. Then when you are happy you can have it give you a map and images of what you two just created. I am pretty sure if I asked the AI I use if thats a fire worm it'd say no and give me a pic of a dragon and tell me to quit worrying about something that small. lol

Just chiming in to the ai talk, I work at an AI consulting company. It can do a lot of awesome things and is definitely getting better every day. With that said, you have to know where and how to use it. My two best tips are to provide context for the question you're asking(so saying I own a ___ gallon fish tank with XYZ, etc. and then giving the question) and to tell it to research the web and provide sources. Both should help with the LLM providing actually useful answers and to help it stop hallucinating. Bonus points if you give it some reputable sites to search through(copy and paste the website directly), if it cites it should take you to the page directly. Last thing I'll say is that usually the paid versions are better since you get models that are research based(example being chat gpt o3(research and thinking, better if you want to ask questions about, for example, fish keeping) and 4o(better at writing/creativity, but does give you a lot of emojis).

Agreed context is key. I use the premium version of ChatGPT.

seems the movie clip might be too big - won’t play. Here’s another picture.

That looks like a Eunice worm, not a common bristle worm variety. Eunice worms are ambush predators and typically do not eat dead things and leftovers. There are hundreds of types and live in many different marine environments. I would exclude this guy if it were me but it will probably not pose a threat to most tank inhabitants. Small things like copepods and amphipods other worms and possibly fish fry may be in danger.

A few of them popped out during the dip this morning. Hopefully that was it. Thank you.

This looks like a dorvillidae, a cousin to the bristleworm and Very reef safe

Thank you. They looked scary enough and were uninvited so I tossed them - better safe than sorry.
Eunicidae family include bristle worms, dorvillidae, what people call eunice worms, and others, one of the largest distinctions in these worms is their mouth parts. Bristle worms dont have the prey capture apparatus of most of the other eunicidae members. The only thing a bristle worm is going to catch is if its dead or dying. The ones commonly referred to as eunice worms like the bobbit worm and its smaller cousins all have mandibles that pierce into the prey item to hold it in place while they eat it. Dorvillidae have these mouth parts as well. I am unsure why they are referred to as reef safe, its probably based on size as they rarely exceed 1.5" which would make them incapable of harming most fish and corals, clams and most cuc would not be on the menu. There is anecdotal "evidence" that suggests that the white ring just behind the head segment indicates its not dorvillidae, how true that is idk. There are many members of this family and many that stay quite small which could mean they are also "reef safe" but with the proper prey catching parts what prey are they catching? Pods, other more "useful" worms, maybe flat worms? I think better safe than sorry is probably the right choice.

Thanks for that great explanation. I feel like by the time I’m done with this hobby I’ll have an honorary phd in marine biology.

Its part of the Hobby if you get hooked any way. Over the years I have found myself researching all kinds of stuff. I still struggle with chemistry (not good in our hobby) just like in school. Of course, the info I get could be faulty or I may be describing things inaccurately luckily we have a lot of knowledgeable people here to set us straight.

One person that is very knowledgeable in the identification of random critters is @ISpeakForTheSeas they are not always around but usually respond at some point when "summoned".
