Fugida?

Hi all!

I started having small CuC dying in the same part of my tank, near my foundation rock. Then, 2 watchman hobbies died with one day. I witnessed the second goby swim frantically out of the foundation rock cave he built, his body was gray and his head yellow. He appeared to be having a seizure and fell to the sandbed dead in all of 10 seconds.

I am a night owl and started ro periodically check the tank with a red light and saw a worm that was curled in a crevice. Bristle worm traps were empty after dozens of attempts. Couldn't catch him with tweezers as he retracted back to foundation in a flash. Until tonight! I got him.

Can anyone help I.D, please?sorry, pics are post mortem, he grossed me out bad!

The scientific name of this thing should be Alitta succinea

Yea it’s a bristle worm.

Although he wouldn’t have anything to do with why your fish died.
Especially with how you describe the fish darted and twitched and then died that’s very common when fish die from Neurological issues.

I agree common bristle worm not the cause, but would happily dispose of the body for you.
