Firework or Bristleworm?

[Skipbacon]

Can you please check this creature out? He’s rather large while most of my bristleworms are small and peaceful. If I need to relocate this guy to the sump I’d rather do it before it eats my yasha goby. Thank you!

Looks like a large bristleworm. I have many in my entire system. They scavenge for leftovers at feeding time.

Definitely not a firework
