Actually, my spawned and now I have maybe hundred of small coco worms. But after the large red coco worm spawned, it died. I only bought it for a few months and it died after spawning.
When it died, I still didn't know it has spawned, it is only after a few weeks then I saw a lot of red feathery stuff on the underside of my rocks. To my surprise, they were all small red coco worms and a lot of them.
It has been a more than half a year and the baby coco worms are still growing each day. Hopefully they will continue to thrive and grow.
