Hello, I’ve noticed in one of my tanks, all the snails have been disappearing. All that’s left is cleared out shells. My hermits are also gone. I just got this new batch of live rock but it’s only 5 pounds of it, I feel wouldn't a predator need more room than these small holes? My fish are all okay but I notice they don’t go down towards the rock very often. How do I catch it?
Thank you
