Hello, I noticed today that one of my chromis is missing. I checked all the caves and even took the rocks out and I could not find him. I looked at the floor, back of the cabinet and the back of the JBJ nano. its not there. I'm afraid that it dies and was consumed by my cleaners. My question is do you think 6 hermit crabs, 1 damsel, 2 clowns, 1 fire shrimp and 3 turbo snails can devour a small fish within 24 hrs?
