Have a tank with about 90lbs++ live rock and argonite substrate. Was given some wrong information about an Enigneer Goby. Was told he was a good sand sifter but after placing him in the tank, I've released he is making huge tunnels and holes in the substrate which my live rock is resting on top of. Will the live rock sink and settle evenly or is there a chance it could come crashing down and crack the tank?
Any advice would be greatly appreciated.
