Watchmen gobies eat bristle worms?

[madatom]

Why have I not heard of this before? Everyone be like “get a wrasse”….

Funny thing is after I added this yellow watchmen goby to my tank, I hadn’t seen it for like 2 months. Though it was dead.

Then I sold my wrasse cause it was getting way too big for the tank and seemingly knocks over all my frags, and within a couple weeks my watchmen goby is like showing it’s face.

I did not know that. I seems to be that something that will eat anything in the tank, wither fish, coral, pests it's an amazing circle of life.
