These little creatures are inside my filter, live inside my rock work. They’re nocturnal and if I turn on my lights in the middle of the night I catch these little guys crawling all over my rocks as they scramble back inside to hide. These are the best pics I could get

Lucky bugs! The fish should love them.

Phew! I thought it was a pest!
