Arduino ESP8266 how to make FastLED drive 2 different strips with 2 different effects at the same time?

Question

Arduino

Good day,
Tell me how to make the Arduino ESP8266 FastLED library control two different strips with 2 different effects at the same time?
The first tape (something like a white meteor runs in a circle, but there is a constant blue background)
The second tape is lit in blue and after 30 seconds. smoothly turns off for 5 seconds and turns on again for 30
I wrote the code, the first effect works, but as I add the second, the first one stops working, and the second one doesn’t at all.
Help to write correctly

#include "FastLED.h"          // библиотека для работы с лентой

#define LED_COUNT_A 24          // число светодиодов в кольце/ленте
#define LED_COUNT_B 24          // число светодиодов в кольце/ленте2
#define LED_DA 22             // пин, куда подключен DIN 1 ленты
#define LED_DB 21             // пин, куда подключен DIN 2 ленты
#define del 50
int max_bright = 100;         // максимальная яркость (0 - 255)

// ---------------СЛУЖЕБНЫЕ ПЕРЕМЕННЫЕ-----------------
int BOTTOM_INDEX = 0;        // светодиод начала отсчёта
int TOP_INDEX = int(LED_COUNT_A / 2);
int EVENODD = LED_COUNT_A % 2;
struct CRGB leds_a[LED_COUNT_A];
struct CRGB leds_b[LED_COUNT_B];
int ledsX[LED_COUNT_A][3];     //-ARRAY FOR COPYING WHATS IN THE LED STRIP CURRENTLY (FOR CELL-AUTOMATA, MARCH, ETC)

int thishue = 0;             //-FX LOOPS DELAY VAR
int thissat = 255;           //-FX LOOPS DELAY VAR
int idex = 0;                //-LED INDEX (0 to LED_COUNT_A-1
// ---------------СЛУЖЕБНЫЕ ПЕРЕМЕННЫЕ-----------------

void setup()
{
  Serial.begin(9600);              // открыть порт для связи
  LEDS.setBrightness(max_bright);  // ограничить максимальную яркость

  LEDS.addLeds<WS2812B, LED_DA, GRB>(leds_a, LED_COUNT_A);  // настрйоки для ленты A
  LEDS.addLeds<WS2812B, LED_DB, GRB>(leds_b, LED_COUNT_B);  // настрйоки для ленты B

  LEDS.show();
  delay(100);

            leds_b[i].fadeToBlackBy( 64 );  
          }
