Not by a long shot - the whole idea behind this hobby is to enjoy your aquarium and its contents however you wish to enjoy it. You want to create a natural reef go for it. Everyone gets something different out of this hobby, has different tastes, goals and expectations.The whole idea behind this hobby is to recreate the ocean environment. Everything in the tank plays a role in the health/ecology of the tank.
