Fan worm-Sabellidae, calcium tubed variation does well.

Some months back we were on boat collecting trip and I wanted to give a calcium tubeworm or two a go.
I broke a few open including a supposed fan worm and extracted the tubeworm and set them up under some bits of coral.
Two didn’t make it due to my peps,they eat all small animals.
I have had the worm that i could not find in my books called a fan worm,even Jeff from the museum that got it identifide was supprised that it is a fan worm

Any way this one made it and has formed a new cal tube.
