Hello - I have 180 gallon tank with a large saddle back clown, another clown and a magnifcent lo. All large fish 3-5 inches. I added a school of Green chromis - 9 in total. Each day one ends up missing so something is eating them. One was missing a part of his tail. The tank is 6 years old and established. The rock came from the ocean through a retailer. It was full of life - including some bad crabs. Anyway, over the years I'm 100% sure there are no gorilla crabs. However, I have always heard a popping sound in the tank and attributed it to a pistol shrimp. I have never seen a mantis and the large fish have been fine for years. What else can be fish killers in a tank? Bobbit worm lurking somewhere under the rock? Any other hidden killers (nocturnal) I should look for? I don't want to rip the rock apart but I may go searching. I do have a HIGH mortality rate for snail but assume snails just have a high mortality rate...
I have also searched at night with red light and haven't even seen anything that looks dangerous or that's unaccounted for.
What are fish killers in our aquariums that would live at least 6 years?
