Adding Stax Rock to existing tank

[mclaurin]

2 month old tank but had Covid when I put it together and regretting my choices. Have live rock,live sand,2 snowflake clowns,coral beauty,orchid dottyback some hermit crabs and an emerald crab (although he looks brownish to me). Would like to get rid of the the plastic and battleship but the fish seem to adore it. Have 40lbs of Stax Rock I’d like to use to make the tank look better. Do I quarantine the fish in another tank with old filter while I do this? Any help would be much appreciated Leslie

Are you going to glue the rocks? Or are you going to stack them inside the tank?
