this is a fireworm or bristleworm ? Or is there a difference?

also i found this worm i would like to identify

 

I think you may need a closer photo of the 1st worm for a correct ID. The second looks like it may be a "Peanut Worm", which are harmless if that is indeed what it is.

Here is a good site for work (and other) hitchiker IDs: Worm Hitch Hikers

 

The first set of pictures definitely looks bristlewormy to me. Fire worms are actually a type of bristleworm. Fire worms just have hollow bristles that contain a toxin, that can cause irritation and "burning" when touched. Hence the name fireworm.

Most bristleworms are harmless to aquariums. The exception simply is that some larger species can be opportunistic predators. This typically doesn't happen with the smaller "typical" worms that hitchhike in. If you find a big one in there there, I'd take it out just to be safe. The smaller ones can be left alone, as the only thing they will do is eat gunk in your tank. They make a great clean up crew, even though they are ugly as heck.

If you do want them removed, our tank is 5 years old now with a 6 line wrasse living in it from the beginning (technically this is 6 line wrasse 2.0). He and his predecessor have highhandedly taken on any bristleworm they could find. I can't tell you the last time I saw one in our tank. I'm sure some of them died on their own, but that wrasse sure helped. So, if you want them gone, I suggest a more natural means of removal. Some people spend hours pulling on them and trapping them, but I just think that is a waste of time. They are ugly and scary looking, but are typically harmless and beneficial to your tank.

Same goes for the peanut worm. We had one in our tank for the longest time, but it's been a while since I've seen him. They are totally harmless and tend to just stick to their hole eating gunk at night. I wouldn't worry about him. Think of him as a free addition to your tank.

 

excellent link marshallo thx

 

jwin any wrasse would eat those worms i would love to have a mystery wrasse or eight line wrasse or even better both.., )

 

SO.. The moral to the story is if they are small, leave them in there? I have one creeping around that I wasn't going to mess with, but I'm about to move and was going to get rid of it when I remove all my LR. Also looks like a six line is my next fish of choice down the road.

 

If you want it gone and get the opportunity, sure, take it out while you can. But if it doesn't bother you, it won't be a problem. And as maxter said, it looks like any wrasse would take that thing on. We've just had tons of success with a six line. Especially with the not jumping out of the tank part. So far our six lines have been great at that, while other wrasses we've tried haven't been so great...
