While Precor IGR shouldn't harm fish if used appropriately, you would need at miminum to cover the fish tank while spraying and until everything has dried and settled. If its easy to remove the fish before spraying then I would do so, but if not, just covering them with a sheet or fabric to protect from particles getting in the water or filter would be sufficient.
