Bristle worm or worse?

[dreaddinit]

What is this creature? Bad or good?

 

[dreaddinit]

I out two chromis in yesterday and there is only one left that I can tell unless it's hiding very well. Culprit?

 

[chefbill]

That's just a basic beneficial bristle worm. Won't attack a fish unless that fish sick or dead

If your tank is under 100 gallons, the other chromis could be responsible.

Nah, bristle worms are fairly harmless. Some people hate them, some love them.

I liked them to help clean up uneaten food.

Your chromis could be hiding or could have died if you didn't transition him right.

I have many Bristleworms and what I have found is the red seems more pronounced on the ends when they are small, Not a predator to attack a healthy fish. Did you check salinity of the Water in the bag vs your tank, fish can acclimate down pretty quickly but when your tank is higher than what the LFS has it takes longer to acclimate and could be the cause of your fish's demise

Thanks for the replies everyone. I was tripping bad. I had never seen this creature before and then a brand new fish vanished. I panicked.
