A question about christmas tree worm

[firepig36]

I know that christmas tree worms live with sps coral called "porites".My question is that,if the base coral is dead,can I attach other encrusting coral like monti or some kinds of lps?wont they kill worms by covering?and once worms are dead,isnt there any way to restore their population?How do they reproduce?

I really aprreciate your thoughtful and kind answer

To my knowledge, they should be fine even if the coral is dead (though that obviously isn't preferred) - but I'm not sure if they would move from the dead Porites to a live Monti/other coral (my understanding is they tend to pick somewhere to settle and stay there, and they do generally seem to have a strong preference for Porites - though they will settle on other corals occasionally too).

The worms shouldn't be killed by a coral being placed over/growing over them - they should just bore up through the coral.

Once the worms are dead, the way to restore their population is by buying more - they won't come back from the dead. They reproduce through broadcast spawning. To my knowledge, they go through a pelagic stage that lasts for about 2 weeks, and then they settle onto their chosen coral (so these almost certainly won't reproduce successfully in a normal reef tank).

the worms will be fine if you grow a new coral onto the rock, as for them dying, i dont think you can repopulate the rock once they die, which it seems they have a lifespan of 20 - 50 years so i wouldn't worry about it if you keep them well fed
