Claim checked: "Peaceful fish are shrimp-safe" What is supported: outcomes depend on the exact fish species, individual size, shrimp life stage, cover, feeding, intake protection and the tank's goal.

Do next: decide whether the goal is adult display or colony recruitment, then evaluate the exact species.
