New to all this, and recently turned on the lights. Needless to say I have algae growing. The trochus, Atlantic grazers, and hermits are doing their job keeping everything at bay. I have a gobie and a pistol shrimp, who have staked their rock and corner. I want to add a star or nassarius snails to stir the sand, but will they disturb the pistol shrimp or should I care? Kind of don't want to upset the shrimp but do want to stir the sand. Do they just stay away from each other? Any thoughts appreciated or am I over thinking this, lol.
